    在这输入Email关键字，能找到你想要的验证代码

    谢谢呀这是Email验证的吧
    可是
    "^\w+((-\w+)|(\.\w+))*\@\w+((\.|-)\w+)*\.\w+$"该怎么用呢？
    教教俺吧
    可别怪我是白痴，呵呵...
      

  3.   

    Email:   \w+((-\w+)|(\.\w+))*\@\w+((\.|-)\w+)*\.\w
      

  4.   

    密码的：\w{1,n}
    n是密码的长度
      

  5.   

    email 的<asp:RegularExpressionValidator id="RegularExpressionValidator4" runat="server" ErrorMessage="电子信箱输入有错误" Display="Dynamic"
    Font-Size="9pt" ControlToValidate="email" ValidationExpression="\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*"></asp:RegularExpressionValidator>
    密码的<asp:RegularExpressionValidator id="RegularExpressionValidator3" runat="server" ErrorMessage="用户密码有不合法字符" Font-Size="9pt"
    ControlToValidate="pass2" ValidationExpression="^[^<']*"></asp:RegularExpressionValidator>
      

  6.   

    Regex(REGEXP_IS_VALID_EMAIL)).IsMatch(validate)validate:是你要验证的字符串或者网页上添加RequiredFieldValidator控件，设置该控件的ControlToValidator属性为该验证字符串输入框的ID，设置ErrorMessge属性为你要显示的信息，设置InitalValue为该正则表达式，OK

    这是个简单例子：
    <%@ Page Language="C#" %> <html>
     <head>
        <script runat="server">
     
           void ValidateBtn_Click(Object sender, EventArgs e) 
           {
              if (Page.IsValid) 
              {
                 lblOutput.Text = "Page is Valid!";
              }
              else 
              {
                 lblOutput.Text = "Page is InValid!";
              }
           }
     
        </script>
     
     </head>
     <body>
     
        <h3>RegularExpressionValidator Sample</h3>
        <p>
     
        <form runat="server">
     
           <table bgcolor="#eeeeee" cellpadding="10">
              <tr valign="top">
                 <td colspan="3">
                    <asp:Label id="lblOutput" 
                         Text="Enter a 5 digit zip code" 
                         Font-Name="Verdana" 
                         Font-Size="10pt" 
                         runat="server"/>
                 </td>
              </tr>
     
              <tr>
                 <td colspan="3">

                 </td>
              </tr>
              <tr>
                 <td></td>
                 <td>
                    <asp:Button text="Validate"
