如何使用.NET查看微信公众号关注者接口

如何使用.NET查看微信公众号关注者接口，针对这个问题，这篇文章详细介绍了相对应的分析和解答，希望可以帮助更多想解决这个问题的小伙伴找到更简单易行的方法。

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 userdetail  {    public int subscribe { get; set; }    public string openid { get; set; }    public string nickname { get; set; }    public int sex { get; set; }    public string language { get; set; }    public string city { get; set; }    public string province { get; set; }    public string country { get; set; }    public string headimgurl { get; set; }    public int subscribe_time { get; set; }    public string unionid { get; set; }    public string remark { get; set; }    public int groupid { get; set; }    public int[] tagid_list { get; set; }  }

getUser.aspx代码:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="getUser.aspx.cs" Inherits="MyTest.WebUI.Manager.usermsg.getUser" %>

JSon序列化，反序列化

public class JsonEntityExchange where T:new()  {    /// 
    /// json转实体LIST    /// 
    ///     ///     public static List Json2Entitys(string JsonStr)    {      JavaScriptSerializer Serializer = new JavaScriptSerializer();      List objs = Serializer.Deserialize>(JsonStr);      return objs;    }    /// 
    /// json转实体    /// 
    ///     ///     public static T Json2Entity(string json)    {      T obj = Activator.CreateInstance();      using (MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(json)))      {        DataContractJsonSerializer serializer = new DataContractJsonSerializer(obj.GetType());        return (T)serializer.ReadObject(ms);      }    }    ///
