我是靠谱客的博主默默小蜜蜂，最近开发中收集的这篇文章主要介绍微信公众号中用户分组管理.NET实例详解，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

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; }
  }
登录后复制

  public class userlistopenid
  {
    public List<string> openid { get; set; }
  }
登录后复制

 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
  }
