最朴实的WCF入门教程(转载,不跟你扯什么契约行为)

搞过WCF的应该都知道,初学的时候是多么的痛苦。。。我不想多说。。。光是消息队列,消息契约,服务契约就够你理解半天,我还有一篇关于消息队列的转载有需要的可以去看一下。

一、前言

    前面的几个章节介绍了很多理论基础,如:什么是WCF、WCF中的A、B、C。WCF的传输模式。本文从零开始和大家一起写一个小的WCF应用程序Demo。

    大多框架的学习都是从增、删、改、查开始来学习的,我们学习WCF也是一样的。从简单来看(不包括安全、优化等相关问题),WCF的增删改查和WebForm相差无几。WCF只是把具体“实现”写在“Service端”,而“调用”放在了“Client端”。觉得有帮助别忘了点个赞哈,谢谢哦~

二、Demo说明

1)Demo的 “Service端”以本机IIS为宿主,“Client端”以WebForm项目为例。

2)Demo的“Service端”提取数据采用初学者比较容易接受的分层结构进行搭建,分别分为服务层、实体层、数据层。

引用关系如下图所示:

3)Demo以数据库为SqlServer,表User为例(sql语句在下载的压缩包中Init.sql),表结构如下所示:

字段名

列名

数据类型

约束

生成方式

用户编号

UserID

int

主键,必须输入

自动增+1

姓名

Name

varchar(200)

非必须输入

人工输入

密码

Password

varchar(200)

非必须输入

人工输入

描述

Discribe

varchar(800)

非必须输入

人工输入

提交时间

SubmitTime

datetime

非必须输入

人工输入

三、创建Service端宿主

1)创建WCF应用程序命名为:WCF.Demo.Service,如下图:

2)删除默认文件IService.csService.svc。并分别创建增、删、改、查”Add.svc”“Save.svc”“Remove.svc”“Get.svc,Search.svc”,分别对应4个功能的服务应用程序WCF服务应用程序,并创建数据操作层和数据实体层,如下图:

3)增加实体层和数据操作层代码,如下所示:

复制代码
 1     //用户实体
 2     [DataContract]
 3     public class User
 4     {
 5         [DataMember]
 6         public int UserID { get; set; }
 7         [DataMember]
 8         public string UserName { get; set; }
 9         [DataMember]
10         public string Password { get; set; }
11         [DataMember]
12         public string Discribe { get; set; }
13         [DataMember]
14         public DateTime SubmitTime { get; set; }
15     }
16     //数据操作,调用SqlHeler
17     public class User
18     {
19         private static readonly string connectionString = "server=.;database=wcfDemo;uid=sa;pwd=123456;";
20 
21         //添加
22         public static bool Add(Model.User user)
23         {
24             string sql = string.Format("INSERT INTO [dbo].[User]([UserName],[Password],[Discribe],[SubmitTime]) VALUES('{0}','{1}','{2}','{3}')", user.UserName, user.Password, user.Discribe, user.SubmitTime);
25             int result = SqlHelper.ExecuteNonQuery(connectionString, CommandType.Text, sql);
26             if (result > 0)
27                 return true;
28             else
29                 return false;
30         }
31 
32         //修改
33         public static bool Save(Model.User user)
34         {
35             string sql = string.Format("UPDATE [dbo].[User] SET [UserName] = '{0}',[Discribe] = '{2}',[SubmitTime] = '{3}' WHERE UserID = {4}", user.UserName, user.Password, user.Discribe, user.SubmitTime, user.UserID);
36             int result = SqlHelper.ExecuteNonQuery(connectionString, CommandType.Text, sql);
37             if (result > 0)
38                 return true;
39             else
40                 return false;
41         }
42 
43         //删除
44         public static bool Remove(int UserID)
45         {
46             string sql = string.Format("DELETE FROM [dbo].[User] WHERE UserID = {0}", UserID);
47             int result = SqlHelper.ExecuteNonQuery(connectionString, CommandType.Text, sql);
48             if (result > 0)
49                 return true;
50             else
51                 return false;
52         }
53 
54         //获取用户
55         public static Model.User Get(int UserID)
56         {
57             Model.User user = new Model.User();
58             string sql = string.Format("SELECT * FROM [dbo].[User] WHERE UserID = {0}", UserID);
59             DataSet ds = SqlHelper.ExecuteDataset(connectionString, CommandType.Text, sql);
60             if (ds != null && ds.Tables.Count > 0)
61             {
62                 foreach (DataRow dr in ds.Tables[0].Rows)
63                 {
64                     user.UserID = Convert.ToInt32(dr["UserID"]);
65                     user.UserName = dr["UserName"].ToString();
66                     user.Password = dr["Password"].ToString();
67                     user.Discribe = dr["Discribe"].ToString();
68                     user.SubmitTime = Convert.ToDateTime(dr["SubmitTime"]);
69                 }
70             }
71             return user;
72         }
73 
74         //获取用户列表
75         public static List<Model.User> GetUsers()
76         {
77             List<Model.User> Users = new List<Model.User>();
78             string sql = string.Format("SELECT * FROM [dbo].[User]");
79             DataSet ds = SqlHelper.ExecuteDataset(connectionString, CommandType.Text, sql);
80             if (ds != null && ds.Tables.Count > 0)
81             {
82                 foreach (DataTable dt in ds.Tables)
83                 {
84                     foreach (DataRow dr in dt.Rows)
85                     {
86                         Model.User user = new Model.User();
87                         user.UserID = Convert.ToInt32(dr["UserID"]);
88                         user.UserName = dr["UserName"].ToString();
89                         user.Password = dr["Password"].ToString();
90                         user.Discribe = dr["Discribe"].ToString();
91                         user.SubmitTime = Convert.ToDateTime(dr["SubmitTime"]);
92                         Users.Add(user);
93                     }
94                 }
95             }

10         public bool DoWork(Model.User user)
11         {
12             return DAL.User.Add(user);
13         }
14     }
复制代码

 5)修改Save接口的代码和实现,如下所示:

 3     {
 4         [OperationContract]
 5         bool DoWork(Model.User user);
 6     }
 7 
 8     public class Save : ISave
 9     {
10         public bool DoWork(Model.User user)
11         {
12             return DAL.User.Save(user);
13         }
14     }
复制代码

6)修改Remove接口的代码和实现,如下所示:

复制代码
 1     [ServiceContract]
 2     public interface IRemove
 3     {
 4         [OperationContract]
 5         bool DoWork(int UserID);
 6     }
 7     public class Remove : IRemove
 8     {
 9         public bool DoWork(int UserID)
10         {
11             return DAL.User.Remove(UserID);
12         }
13     }
复制代码

7)修改Search接口的代码和实现,如下所示:

复制代码
 1     [ServiceContract]
 2     public interface ISearch
 3     {
 4         [OperationContract]
 5         List<Model.User> DoWork();
 6     }

11         {
12             return DAL.User.Get(UserID);
13         }
14     }
复制代码

四、部署服务端程序

1)将程序发布,并部署到IIS上,设置端口:8080,如下图所示:

2)以Add.svc服务应用程序为目标,测试部署是否成功,成功后如下图所示:

五、创建Client端Web应用程序

新建WebForm项目WCF.Demo.Client,并创建增删改查文件,Add.aspx,Save.aspx,SearchAndRemove.aspx。如下图所示:

六、使用SvcUtil.exe生成客户端代码和配置

SvcUtil.exe是一个VS命令行工具,该工具位于:C:\Program Files\Microsoft  SDKs\Windows\v7.0A\bin 或 C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\bin\一般情况下我们将SvcUtil.exe添加到VS开发工具中方便以后的运用(也可直接使用该命令行工具)。

1)在VS中的 Tools菜单---选择External Tools,打开管理窗口如下图所示:

在Title中输入SvcUtil,Command中选择SvcUtil.exe全路径,Initial  directory栏选择生成的客户端代码和配置文件所放的目录(此处为解决方案所在目录),选上Prompt for arguments,不选上Close on  exit。点击OK.

2)添加完成后,在VS的工具下会出现这个菜单。如下图所示:

3)在Client端添加对服务的引用。打开SvUtil工具,在Arguments里填写服务的地址,如下图:

点击OK后出现下图,说明代码类和配置文件生成成功(在解决方案目标下),如下图所示:

此时代理类和配置文件被下载到解决方案的物理目录中,如下图所示:

七、在Client端使用代理类与配置

将代理类从服务端的物理目录拷贝出来,放到Client端,并适当的修改代码,加入自己需要的名称空间,如下图所示:

使用代码如下所示:

复制代码
 1     //增加
 2     public partial class Add : System.Web.UI.Page
 3     {
 4         Service.AddClient addClient = new Service.AddClient();
 5         protected void Page_Load(object sender, EventArgs e)
 6         {
 7 
 8         }
 9 
10         //提交
11         protected void btnSubmit_Click(object sender, EventArgs e)
12         {
13             Model.User user = new Model.User();
14             user.UserName = this.txtUserName.Text;
15             user.Password = this.txtPassword.Text;
16             user.Discribe = this.txtDiscribe.Text;
17             user.SubmitTime = System.DateTime.Now;
18             addClient.DoWork(user);
19             Response.Write("添加成功!");
20         }
21     }
22     //修改
23     public partial class Save : System.Web.UI.Page
24     {
25         Service.SaveClient saveClient = new Service.SaveClient();
26         Service.GetClient getClient = new Service.GetClient();
27         protected void Page_Load(object sender, EventArgs e)
28         {
29             if (!Page.IsPostBack && !string.IsNullOrEmpty(Request.QueryString["UserID"]))
30             {
31                 GetUser();
32             }
33         }
34 
35         protected void GetUser()
36         {
37             int UserID = Convert.ToInt32(Request.QueryString["UserID"]);
38             Model.User user = getClient.DoWork(UserID);
39             this.txtUserName.Text = user.UserName;
40             this.txtDiscribe.Text = user.Discribe;
41         }
42 
43         //提交
44         protected void btnSubmit_Click(object sender, EventArgs e)
45         {
46             int UserID = Convert.ToInt32(Request.QueryString["UserID"]);
47             Model.User user = getClient.DoWork(UserID);
48             user.UserName = this.txtUserName.Text;
49             user.Discribe = this.txtDiscribe.Text;
50             saveClient.DoWork(user);
51             Response.Write("修改成功!");
52         }
53     }
54     //列表及删除
55     public partial class SearchAndRemove : System.Web.UI.Page
56     {
57         Service.SearchClient searchClient = new Service.SearchClient();
58         Service.RemoveClient removeClient = new Service.RemoveClient();
59         protected void Page_Load(object sender, EventArgs e)
60         {
61             if (!Page.IsPostBack)
62             {
63                 GetUsers();
64             }
65         }
66 
67         protected void GetUsers()
68         {
69             this.repUsers.DataSource = searchClient.DoWork();
70             this.repUsers.DataBind();
71         }
72 
73         protected void lbtnRemoveCommand(object sender, CommandEventArgs e)
74         {
75             int UserID = Convert.ToInt32(e.CommandName);
76             removeClient.DoWork(UserID);
77             Response.Write("删除成功~");
78             GetUsers();
79         }
80     }
复制代码

将生成的配置文件中的 <system.serviceModel>复制到Client的Web.config中,代码如下:

一、前言

    前面的几个章节介绍了很多理论基础,如:什么是WCF、WCF中的A、B、C。WCF的传输模式。本文从零开始和大家一起写一个小的WCF应用程序Demo。

    大多框架的学习都是从增、删、改、查开始来学习的,我们学习WCF也是一样的。从简单来看(不包括安全、优化等相关问题),WCF的增删改查和WebForm相差无几。WCF只是把具体“实现”写在“Service端”,而“调用”放在了“Client端”。觉得有帮助别忘了点个赞哈,谢谢哦~

二、Demo说明

1)Demo的 “Service端”以本机IIS为宿主,“Client端”以WebForm项目为例。

2)Demo的“Service端”提取数据采用初学者比较容易接受的分层结构进行搭建,分别分为服务层、实体层、数据层。

引用关系如下图所示:

3)Demo以数据库为SqlServer,表User为例(sql语句在下载的压缩包中Init.sql),表结构如下所示:

字段名

列名

数据类型

约束

生成方式

用户编号

UserID

int

主键,必须输入

自动增+1

姓名

Name

varchar(200)

非必须输入

人工输入

密码

Password

varchar(200)

非必须输入

人工输入

描述

Discribe

varchar(800)

非必须输入

人工输入

提交时间

SubmitTime

datetime

非必须输入

人工输入

三、创建Service端宿主

1)创建WCF应用程序命名为:WCF.Demo.Service,如下图:

2)删除默认文件IService.csService.svc。并分别创建增、删、改、查”Add.svc”“Save.svc”“Remove.svc”“Get.svc,Search.svc”,分别对应4个功能的服务应用程序WCF服务应用程序,并创建数据操作层和数据实体层,如下图:

3)增加实体层和数据操作层代码,如下所示:

复制代码
 1     //用户实体
 2     [DataContract]
 3     public class User
 4     {
 5         [DataMember]
 6         public int UserID { get; set; }
 7         [DataMember]
 8         public string UserName { get; set; }
 9         [DataMember]
10         public string Password { get; set; }
11         [DataMember]
12         public string Discribe { get; set; }
13         [DataMember]
14         public DateTime SubmitTime { get; set; }
15     }
16     //数据操作,调用SqlHeler
17     public class User
18     {
19         private static readonly string connectionString = "server=.;database=wcfDemo;uid=sa;pwd=123456;";
20 
21         //添加
22         public static bool Add(Model.User user)
23         {
24             string sql = string.Format("INSERT INTO [dbo].[User]([UserName],[Password],[Discribe],[SubmitTime]) VALUES('{0}','{1}','{2}','{3}')", user.UserName, user.Password, user.Discribe, user.SubmitTime);
25             int result = SqlHelper.ExecuteNonQuery(connectionString, CommandType.Text, sql);
26             if (result > 0)
27                 return true;
28             else
29                 return false;
30         }
31 
32         //修改
33         public static bool Save(Model.User user)
34         {
35             string sql = string.Format("UPDATE [dbo].[User] SET [UserName] = '{0}',[Discribe] = '{2}',[SubmitTime] = '{3}' WHERE UserID = {4}", user.UserName, user.Password, user.Discribe, user.SubmitTime, user.UserID);
36             int result = SqlHelper.ExecuteNonQuery(connectionString, CommandType.Text, sql);
37             if (result > 0)
38                 return true;
39             else
40                 return false;
41         }
42 
43         //删除
44         public static bool Remove(int UserID)
45         {
46             string sql = string.Format("DELETE FROM [dbo].[User] WHERE UserID = {0}", UserID);
47             int result = SqlHelper.ExecuteNonQuery(connectionString, CommandType.Text, sql);
48             if (result > 0)
49                 return true;
50             else
51                 return false;
52         }
53 
54         //获取用户
55         public static Model.User Get(int UserID)
56         {
57             Model.User user = new Model.User();
58             string sql = string.Format("SELECT * FROM [dbo].[User] WHERE UserID = {0}", UserID);
59             DataSet ds = SqlHelper.ExecuteDataset(connectionString, CommandType.Text, sql);
60             if (ds != null && ds.Tables.Count > 0)
61             {
62                 foreach (DataRow dr in ds.Tables[0].Rows)
63                 {
64                     user.UserID = Convert.ToInt32(dr["UserID"]);
65                     user.UserName = dr["UserName"].ToString();
66                     user.Password = dr["Password"].ToString();
67                     user.Discribe = dr["Discribe"].ToString();
68                     user.SubmitTime = Convert.ToDateTime(dr["SubmitTime"]);
69                 }
70             }
71             return user;
72         }
73 
74         //获取用户列表
75         public static List<Model.User> GetUsers()
76         {
77             List<Model.User> Users = new List<Model.User>();
78             string sql = string.Format("SELECT * FROM [dbo].[User]");
79             DataSet ds = SqlHelper.ExecuteDataset(connectionString, CommandType.Text, sql);
80             if (ds != null && ds.Tables.Count > 0)
81             {
82                 foreach (DataTable dt in ds.Tables)
83                 {
84                     foreach (DataRow dr in dt.Rows)
85                     {
86                         Model.User user = new Model.User();
87                         user.UserID = Convert.ToInt32(dr["UserID"]);
88                         user.UserName = dr["UserName"].ToString();
89                         user.Password = dr["Password"].ToString();
90                         user.Discribe = dr["Discribe"].ToString();
91                         user.SubmitTime = Convert.ToDateTime(dr["SubmitTime"]);
92                         Users.Add(user);
93                     }
94                 }
95             }
96             return Users;

 9     {
10         public bool DoWork(Model.User user)
11         {
12             return DAL.User.Add(user);
13         }
14     }
复制代码

 5)修改Save接口的代码和实现,如下所示:

 1     [ServiceContract]
 2     public interface ISave
 3     {
 4         [OperationContract]
 5         bool DoWork(Model.User user);
 6     }
 7 
 8     public class Save : ISave
 9     {
10         public bool DoWork(Model.User user)
11         {
12             return DAL.User.Save(user);
13         }
14     }
复制代码

6)修改Remove接口的代码和实现,如下所示:

复制代码
 1     [ServiceContract]
 2     public interface IRemove
 3     {
 4         [OperationContract]
 5         bool DoWork(int UserID);
 6     }
 7     public class Remove : IRemove
 8     {
 9         public bool DoWork(int UserID)
10         {
11             return DAL.User.Remove(UserID);
12         }
13     }
复制代码

7)修改Search接口的代码和实现,如下所示:

复制代码
 1     [ServiceContract]
 2     public interface ISearch
 3     {
 4         [OperationContract]
 5         List<Model.User> DoWork();
 6     }
 7 
 8     public class Search : ISearch
 9     {
10         List<Model.User> ISearch.DoWork()
11         {

 9     {
10         public Model.User DoWork(int UserID)
11         {
12             return DAL.User.Get(UserID);
13         }
14     }
复制代码

四、部署服务端程序

1)将程序发布,并部署到IIS上,设置端口:8080,如下图所示:

2)以Add.svc服务应用程序为目标,测试部署是否成功,成功后如下图所示:

五、创建Client端Web应用程序

新建WebForm项目WCF.Demo.Client,并创建增删改查文件,Add.aspx,Save.aspx,SearchAndRemove.aspx。如下图所示:

六、使用SvcUtil.exe生成客户端代码和配置

SvcUtil.exe是一个VS命令行工具,该工具位于:C:\Program Files\Microsoft  SDKs\Windows\v7.0A\bin 或 C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\bin\一般情况下我们将SvcUtil.exe添加到VS开发工具中方便以后的运用(也可直接使用该命令行工具)。

1)在VS中的 Tools菜单---选择External Tools,打开管理窗口如下图所示:

在Title中输入SvcUtil,Command中选择SvcUtil.exe全路径,Initial  directory栏选择生成的客户端代码和配置文件所放的目录(此处为解决方案所在目录),选上Prompt for arguments,不选上Close on  exit。点击OK.

2)添加完成后,在VS的工具下会出现这个菜单。如下图所示:

3)在Client端添加对服务的引用。打开SvUtil工具,在Arguments里填写服务的地址,如下图:

点击OK后出现下图,说明代码类和配置文件生成成功(在解决方案目标下),如下图所示:

此时代理类和配置文件被下载到解决方案的物理目录中,如下图所示:

七、在Client端使用代理类与配置

将代理类从服务端的物理目录拷贝出来,放到Client端,并适当的修改代码,加入自己需要的名称空间,如下图所示:

使用代码如下所示:

复制代码
 1     //增加
 2     public partial class Add : System.Web.UI.Page
 3     {
 4         Service.AddClient addClient = new Service.AddClient();
 5         protected void Page_Load(object sender, EventArgs e)
 6         {
 7 
 8         }
 9 
10         //提交
11         protected void btnSubmit_Click(object sender, EventArgs e)
12         {
13             Model.User user = new Model.User();
14             user.UserName = this.txtUserName.Text;
15             user.Password = this.txtPassword.Text;
16             user.Discribe = this.txtDiscribe.Text;
17             user.SubmitTime = System.DateTime.Now;
18             addClient.DoWork(user);
19             Response.Write("添加成功!");
20         }
21     }
22     //修改
23     public partial class Save : System.Web.UI.Page
24     {
25         Service.SaveClient saveClient = new Service.SaveClient();
26         Service.GetClient getClient = new Service.GetClient();
27         protected void Page_Load(object sender, EventArgs e)
28         {
29             if (!Page.IsPostBack && !string.IsNullOrEmpty(Request.QueryString["UserID"]))
30             {
31                 GetUser();
32             }
33         }
34 
35         protected void GetUser()
36         {
37             int UserID = Convert.ToInt32(Request.QueryString["UserID"]);
38             Model.User user = getClient.DoWork(UserID);
39             this.txtUserName.Text = user.UserName;
40             this.txtDiscribe.Text = user.Discribe;
41         }
42 
43         //提交
44         protected void btnSubmit_Click(object sender, EventArgs e)
45         {
46             int UserID = Convert.ToInt32(Request.QueryString["UserID"]);
47             Model.User user = getClient.DoWork(UserID);
48             user.UserName = this.txtUserName.Text;
49             user.Discribe = this.txtDiscribe.Text;
50             saveClient.DoWork(user);
51             Response.Write("修改成功!");
52         }
53     }
54     //列表及删除
55     public partial class SearchAndRemove : System.Web.UI.Page
56     {
57         Service.SearchClient searchClient = new Service.SearchClient();
58         Service.RemoveClient removeClient = new Service.RemoveClient();
59         protected void Page_Load(object sender, EventArgs e)
60         {
61             if (!Page.IsPostBack)
62             {
63                 GetUsers();
64             }
65         }
66 
67         protected void GetUsers()
68         {
69             this.repUsers.DataSource = searchClient.DoWork();
70             this.repUsers.DataBind();
71         }
72 
73         protected void lbtnRemoveCommand(object sender, CommandEventArgs e)
74         {
75             int UserID = Convert.ToInt32(e.CommandName);
76             removeClient.DoWork(UserID);
77             Response.Write("删除成功~");
78             GetUsers();
79         }
80     }
复制代码

将生成的配置文件中的 <system.serviceModel>复制到Client的Web.config中,代码如下:
