如何构建ASP.NET微信公众号中的用户分组管理web页面

如何构建ASP.NET微信公众号中的用户分组管理web页面，相信很多没有经验的人对此束手无策，为此本文总结了问题出现的原因和解决方法，通过这篇文章希望你能解决这个问题。

Model层实体类:

 public class UserList { public string total { get; set; } public string count { get; set; } public userlistopenid data { get; set; } public string next_openid { get; set; } } public class userlistopenid { public List openid { get; set; } }

 public class WxGroupsInfo { public string Group_ID { get; set; }//分组编号 public string Group_Name { get; set; }//分组名称 public string Group_Count { get; set; }//分组人数 }

WX.aspx内容:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WX.aspx.cs" Inherits="test.WX" %>
