这篇文章主要介绍了asp.net微信开发中有关高级群发图文的相关内容，需要的朋友可以参考下
上一篇介绍了如何群发文本消息，本篇将介绍如何群发图文信息，上传图文信息所需的素材，界面如下：
选择素材
新建图文素材
确认选择
刷新
删除素材
本类型素材总数量为：
本次获取的素材数量为：
后台代码如下：
///
/// 绑定图文素材列表
///
private void BindNewsSucaiList()
{
WeiXinServer wxs = new WeiXinServer();
string res = "";
///从缓存读取accesstoken
string Access_token = Cache["Access_token"] as string;
if (Access_token == null)
{
//如果为空，重新获取
Access_token = wxs.GetAccessToken();
//设置缓存的数据7000秒后过期
Cache.Insert("Access_token", Access_token, null, DateTime.Now.AddSeconds(7000), System.Web.Caching.Cache.NoSlidingExpiration);
}
string Access_tokento = Access_token.Substring(17, Access_token.Length - 37);
string posturl = "https://api.weixin.qq.com/cgi-bin/material/batchget_material?access_token=" + Access_tokento;
//POST数据例子： POST数据例子：{"type":TYPE,"offset":OFFSET,"count":COUNT}
string postData = "{\"type\":\"news\",\"offset\":\"0\",\"count\":\"20\"}";
res = wxs.GetPage(posturl, postData);
//使用前需要引用Newtonsoft.json.dll文件
JObject jsOnObj= JObject.Parse(res);
int groupsnum = jsonObj["item"].Count();
List newssucaiitemlist = new List();
List WxNewsSuCaiItemlist = new List();
for (int i = 0; i 0)
{
for (int j = 0; j 再来看看，新建单图文信息界面：
新建单图文上传封面，删除封面的代码如下：

为什么叫群发任务提交成功或失败，因为将信息提交给微信服务器，微信服务器还需审核，审核过程中也有可能审核不通过，不给于群发，所以我起名叫这个，嘿嘿，随便你们怎么起。。。。。
///
/// 微信已群发消息实体类，用于记录已群发消息的条数，信息实体
///
public class WxMassInfo
{
public int WxMassNo { get; set; }//群发消息编号，数据库自增列
public string title { get; set; }//图文消息的标题，若消息是文本类型，此项不显示
public string ImageUrl { get; set; }//图片地址，若消息是文本类型，此项不显示
public string type { get; set; }//消息的类型，文本，图文，图片，语音，视频
public string contents { get; set; }//文本消息的内容，图文消息的正文
public string massObject { get; set; }//群发对象
public string massStatus { get; set; }//群发状态
public string massMessageID{ get; set; }//群发成功后返回的消息ID
public string massDate { get; set; }//群发日期时间
}
以上就是本文的全部内容，希望对大家的学习有所帮助。
