实现效果：客户输入邮箱地址，向客户邮箱中发送一条验证码（有效时间为20分钟），客户根据邮箱中的验证码，输入验证，并进行判断

实现效果图：

页面代码：

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        请输入接收地址：<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
        <%-- 对输入邮箱格式的正确与否进行提示 --%>
        <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label><br />
        <asp:Button ID="Button1" runat="server" Text="获取验证码" /><br />
        请输入邮箱验证码：<asp:TextBox ID="TextBox4" runat="server"></asp:TextBox>
        <asp:Button ID="Button2" runat="server" Text="判断" /><br />
        <%-- 验证正确进行提醒 --%>
        <asp:Label ID="Label3" runat="server" Text="Label"></asp:Label><br />
        <asp:HiddenField ID="HiddenField1" runat="server" />
    </div>
    </form>
</body>
</html>
<script type="text/javascript">
    //正则表达式，对邮箱格式进行判断
    document.getElementById("TextBox1").onkeyup = function () {
        var s = document.getElementById("TextBox1").value;
        if (/^[A-Za-z\d]+([-_.][A-Za-z\d]+)*@([A-Za-z\d]+[-.])+[A-Za-z\d]{2,4}$/.test(s)) {
            document.getElementById("Label1").innerText = "邮箱正确";
        }
        else
        {
            document.getElementById("Label1").innerText = "邮箱错误";
        }
    }
   
</script>
