在.NET微信公众公众中进行用户分组管理的步骤

本文实例为大家分享了.NET微信用户分组管理代码，供大家参考，具体内容如下

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<string> 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
 }
