【毕业设计】注册功能完成

嘿嘿，今天的进度明显要比昨天快一些。一个上午已经将注册功能完成了。

具体步骤如下：

在Login.aspx页面的表格中添加一个注册按钮

新建注册页面Regist.aspx

 

在注册页面后台修改代码

1. using System;
2. using System.Collections;
3. using System.Configuration;
4. using System.Data;
5. using System.Linq;
6. using System.Web;
7. using System.Web.Security;
8. using System.Web.UI;
9. using System.Web.UI.HtmlControls;
10. using System.Web.UI.WebControls;
11. using System.Web.UI.WebControls.WebParts;
12. using System.Xml.Linq;
13. using Layer.BlogDesignEntities;
14. using Layer.BlogDesignLogic.UserBLL;
15.  
16. public partial class Regist : System.Web.UI.Page
17. {
18.     protected void Page_Load(object sender, EventArgs e)
19.     {
20.  
21.     }
22.     protected void ButtonCancel_Click(object sender, EventArgs e)
23.     {
24.         Response.Redirect("Default.aspx");
25.     }
26.     protected void ButtonSubmit_Click(object sender, EventArgs e)
27.     {
28.         IUserBLL user = new UserBLL();
29.         UserInfo userInfo = new UserInfo();
30.  
31.         userInfo.UserName = TextBoxUserName.Text;
32.         userInfo.PassWord = TextBoxPassWord.Text;
33.         userInfo.UserMail = TextBoxEmail.Text;
34.         userInfo.UserRight = 0;
35.  
36.         if (user.CreatUser(userInfo))
37.         {
38.             Response.Write("注册成功！");
39.         }
40.         else
41.         {
42.             Response.Write("注册失败！");
43.         }
44.     }
45. }

在用户数据层中添加创建用户方法

接口

1. using System;
2. using System.Collections.Generic;
3. using System.Linq;
4. using System.Text;
5. using Layer.BlogDesignEntities;
6.  
7. namespace Layer.BlogDesignDataAccess.UserDAL
8. {
9.     /// <summary>
10.     /// 用户实体数据层接口
11.     /// </summary>
12.     public interface IUserDAL
13.     {
14.         /// <summary>
15.         /// 获取用户信息
16.         /// </summary>
17.         /// <param name="uid">用户名称</param>
18.         /// <returns>用户信息</returns>
19.         UserInfo getUserInfo(string userName);
20.  
21.         /// <summary>
22.         /// 添加用户
23.         /// </summary>
24.         /// <param name="userInfo">用户信息</param>
25.         void creatUser(UserInfo useInfo);
26.  
27.         
28.     }
29. }

实现

1.  
2. void IUserDAL.creatUser(UserInfo userInfo)
3. {
4.     string strCmd = "insert into Users(PassWord,UserName,UserMail,UserRight) values(@PassWord,@UserName,@UserMail,@UserRight)";
5.  
6.     conn = new SqlConnection(strConn);
7.  
8.     conn.Open();
9.     cmd = conn.CreateCommand();
10.     cmd.CommandText=strCmd;
11.  
12.     SqlParameter p;
13.     object val;
14.  
15.  
16.     val = userInfo.PassWord;
17.     p = new SqlParameter("@PassWord", SqlDbType.Char, 20);
18.     p.Direction = ParameterDirection.Input;
19.     p.Value = val;
20.     cmd.Parameters.Add(p);
21.  
22.     val = userInfo.UserName;
23.     p = new SqlParameter("@UserName", SqlDbType.Char, 20);
24.     p.Direction = ParameterDirection.Input;
25.     p.Value = val;
26.     cmd.Parameters.Add(p);
27.  
28.     val = userInfo.UserMail;
29.     p = new SqlParameter("@UserMail", SqlDbType.Char, 50);
30.     p.Direction = ParameterDirection.Input;
31.     p.Value = val;
32.     cmd.Parameters.Add(p);
33.  
34.     val = userInfo.UserRight;
35.     p = new SqlParameter("@UserRight", SqlDbType.Int);
36.     p.Direction = ParameterDirection.Input;
37.     p.Value = val;
38.     cmd.Parameters.Add(p);
39.  
40.     cmd.Connection = conn;
41.     cmd.ExecuteNonQuery();
42. }

 

在用户逻辑层添加创建用户方法

接口

1. /// <summary>
2. /// 创建用户
3. /// </summary>
4. /// <param name="Use">欲用户信息</param>
5. /// <returns>创建是否成功呢</returns>
6. bool CreatUser(UserInfo Use);
7.  
8.  
9. /// <summary>
10. /// 检查注册信息是否重复
11. /// </summary>
12. /// <param name="Use">注册信息</param>
13. /// <returns>是否重复</returns>
14. bool creatUserCheck(UserInfo Use);

方法

1. bool IUserBLL.CreatUser(UserInfo Use)
2.       {
3.  
4.           IUserBLL UserB = new UserBLL();
5.           IUserDAL User = new UserDAL();
6.           if (Use.UserName.Trim().Equals(" "))
7.           {
8.               return false;
9.           }
10.           else
11.           {
12.               if (Use.PassWord.Trim().Equals(" "))
13.               {
14.                   return false;
15.               }
16.               else
17.               {
18.                   if (UserB.creatUserCheck(Use))
19.                   {
20.                       User.creatUser(Use);
21.                       return true;
22.                   }
23.                   else
24.                   {
25.                       return false;
26.                   }
27.               }
28.           }
29.       }
30.  
31.       bool IUserBLL.creatUserCheck(UserInfo Use)
32.       {
33.  
34.           IUserDAL User = new UserDAL();
35.           UserInfo ue = new UserInfo();
36.           ue = User.getUserInfo(Use.UserName);
37.           if ((int)ue.UserId==0)
38.           {
39.               return true;
40.           }
41.           else
42.           {
43.               return false;
44.           }
45.       }

 

运行结果
