注意RequiredFieldValidator 控件后面的*，如果不加*自己试试会出现什么效果；）

下面是此页面的后台代码：

protected void loginButton_Click(object sender, EventArgs e)

{

try

{

//创建数据库连接

SqlConnection con = db.CreateConnection();

//打开数据库

con.Open();

//建立插入的SQL语句

string strsql = "insert into login(uname, upass, email, phone, addr) values('" + unameTextBox.Text + "', '" + passwordTextBox.Text + "', '" + emailTextBox.Text + "', '" + phoneTextBox.Text + "', '" + addressTextBox.Text + "' )";

//创建Sqlcommd命令控件

SqlCommand cmd = new SqlCommand(strsql, con);

//执行sqlcommand控件，不返回任何数据

cmd.ExecuteNonQuery();

con.Close();

Response.Redirect("login.aspx");

}

catch (Exception ee)

{

Response.Write("<script>alert('用户名存在，请选择其他用户名')</script>");

}

}

当然，还需要一个连接数据库的类：

using System;

using System.Data;

using System.Configuration;

using System.Web;

using System.Web.Security;

using System.Web.UI;

using System.Web.UI.WebControls;

using System.Web.UI.WebControls.WebParts;

using System.Web.UI.HtmlControls;

using System.Data.SqlClient;

/// <summary>

/// db 的摘要说明

/// </summary>

public class db

{

public db()

{

}

public static SqlConnection CreateConnection()

{

SqlConnection con = new SqlConnection("Data Source=lacalhost;Initial Catalog=message;Integrated Security=True;");

return con;

}

}
