WCF 客户端调用服务操作的两种方法

本节的主要内容:1、通过代理类的方式调用服务操作。2、通过通道的方式调用服务操作。3、代码下载

一、通过代理类的方式调用服务操作(两种方式添加代理类)

1.手动编写代理类,如下:

客户端契约:

 1 using System;
 2 using System.Collections.Generic;
 3 using System.Linq;
 4 using System.Text;
 5 
 6 using System.ServiceModel;
 7 namespace y.WcfFirst.Client.Proxys
 8 {
 9     [ServiceContract]
10     public interface IHello
11     {
12         [OperationContract]
13         string Say(string name);
14     }
15 }
View Code

客户端代理类:

 1 using System;
 2 using System.Collections.Generic;
 3 using System.Linq;
 4 using System.Text;
 5 
 6 using System.ServiceModel;
 7 using System.ServiceModel.Channels;
 8 namespace y.WcfFirst.Client.Proxys
 9 {
10     public class HelloProxy:ClientBase<IHello>,IHello
11     {
12         public HelloProxy()
13             : base()
14         {
15         }
16 
17         public string Say(string name)
18         {
19             return base.Channel.Say(name);
20         }
21     }
22 }
View Code

客户端app.config文件:

 1 <?xml version="1.0" encoding="utf-8" ?>
 2 <configuration>
 3   <system.serviceModel>
 4     <client>
 5       <endpoint name="wcfFirst"
 6                  address="net.tcp://localhost:6666/hello"
 7                  binding="netTcpBinding"
 8                  contract="y.WcfFirst.Client.Proxys.IHello"></endpoint>
 9     </client>
10   </system.serviceModel>
11 </configuration>
View Code

客户端的调用:

1 using (HelloProxy proxy = new HelloProxy())
2                  {
3                     Console.WriteLine("Recevie from Server:{0}", proxy.Say(name));
4                     proxy.Close();
5                  }
View Code

2.通过Metadata方式产生代理类。

服务端需要对app.config进行配置如下:

客户端的操作步骤:先运行服务端(host)。

a.在客户端点击Add Service Reference按钮,添加Service引用。如下图:

b.输入Address地址:http://localhost:8888,点击"GO",获取服务操作。并且重命名Namespace,如下图:

c.客户端对代理类的调用。

1  using (HelloClient clientProxy = new HelloClient())
2                  {
3                      Console.WriteLine("Recevie from Server:{0}", clientProxy.Say(name));
4                      clientProxy.Close();
5                  }

二、通过通道方式调用服务操作

1.客户端契约,如下:

 1 using System;
 2 using System.Collections.Generic;
 3 using System.Linq;
 4 using System.Text;
 5 
 6 using System.ServiceModel;
 7 namespace y.WcfFirst.ClientChannel.Proxy
 8 {
 9     [ServiceContract]
10     public interface IHello
11     {
12         [OperationContract]
13         string Say(string name);
14     }
15 }
View Code

2.客户端配置文件的设置:如下:

 1 <?xml version="1.0" encoding="utf-8" ?>
 2 <configuration>
 3   <system.serviceModel>
 4     <client>
 5       <endpoint name="wcfFirst"
 6                  address="net.tcp://localhost:6666/hello"
 7                  binding="netTcpBinding"
 8                  contract="y.WcfFirst.ClientChannel.Proxy.IHello"></endpoint>
 9     </client>
10   </system.serviceModel>
11 </configuration>
View Code

3.客户端调用服务操作:如下:

1 ChannelFactory<IHello> factory = new ChannelFactory<IHello>("wcfFirst");
2                 IHello channelProxy = factory.CreateChannel();
3                 using(channelProxy as IDisposable)
4                 {
5                     Console.WriteLine("Recevie from Server:{0}", channelProxy.Say(name));
6                 }
