写个页面检查阿里云的账号存在与否
之前无聊写了个阿里云账号注册的页面，主要是检查账号是否存在，现在分享下：
主要通过webrequest实现：
1. 写个阿里云邮箱类：
using System;
using System.Collections.Generic;
using System.Web;
/// <summary>
/// Summary description for AliEmal
/// </summary>
public class AliEmail
{
public ContentClass content;
public bool hasError;
}
public class ContentClass
{
public string message;
public int status;
public bool success;
}
2. 写个邮箱验证类：
using System;
using System.Collections.Generic;
using System.Net;
using System.Net.Mail;
using System.Text;
using System.Text.RegularExpressions;
using System.Web;
/// <summary>
/// Summary description for Util
/// </summary>
public class AliUtil
{
public AliUtil()
{ }
//
// TODO: Add constructor logic here
//

3. 写个简单的前台验证页面：
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="AliCheck.aspx.cs" Inherits="AliCheck" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<div>
阿里云邮箱：
<asp:TextBox ID="AliEmailName" runat="server"></asp:TextBox>
<asp:Button ID="Check" runat="server" Text="检查是否存在" OnClick="Check_Click" />
<div style="color:red;" id="showError" runat="server"></div>
</div>
</div>
</form>
</body>
</html>
