Ajax邮箱、用户名唯一性验证实例代码

废话不多说了，直接给大家贴代码了，具体代码如下所示：

reg.ashx代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
namespace WebT1.Ti.html2
{
  /// 

  /// reg 的摘要说明
  /// 
  public class reg : IHttpHandler
  {
    public void ProcessRequest(HttpContext context)
    {
      if (context.Request["email"] != null)
      {
        string strEmail = context.Request["email"];
        List lstUser = DataService.GetUserList();
        var v = lstUser.Where(p => p.Email == strEmail);
        int iCount = 0;
        if (v.Count() > 0)
        {
          iCount = 1;
        }
        context.Response.ContentType = "text/plain";
        context.Response.Write(iCount.ToString());
      }
    }
    public bool IsReusable
    {
      get
      {
        return false;
      }
    }
  }
  public class DataService
  {
    /// 

    /// 模拟已注册用户数据
    /// 
    public static List GetUserList()
    {
      var list = new List();
      list.Add(new UserModel() { Email = "[email protected]" });
      list.Add(new UserModel() { Email = "[email protected]" });
      list.Add(new UserModel() { Email = "[email protected]" });
      list.Add(new UserModel() { Email = "[email protected]" });
      list.Add(new UserModel() { Email = "[email protected]" });
      return list;
    }
  }
  public class UserModel
  {
    public string Email { get; set; }
  }
}
