微信公共平臺開發-（.net實現）4--發送圖文消息

  以前說了讓微信發送給關注咱們的粉絲普通的文本信息,下面咱們來看看如何發送圖文信息,須要注意的是這裏說的是,讓微信發給咱們,而不是咱們拍個圖片發給微信處理,上傳圖片在之後的再講.下面是發送圖文消息的函數,涉及title(標題),description(摘要),picurl(圖片),連接 (url)幾個關鍵的參數:

格式以下：（此爲多圖文形式）

其實格式呢就和上篇http://www.cnblogs.com/QLJ1314/p/3855371.html格式同樣。

 1 protected string sendPicTextMessage(Msg _mode,string title,string description,string picurl,string url)
 2     {
 3        
 4         string res = string.Format(@"<xml>
 5                                             <ToUserName><![CDATA[{0}]]></ToUserName>
 6                                             <FromUserName><![CDATA[{1}]]></FromUserName>
 7                                             <CreateTime>{2}</CreateTime>//時間，能夠轉成int類型，相似與時間戳
 8                                             <MsgType><![CDATA[news]]></MsgType>
 9                                             <ArticleCount>1</ArticleCount>//數量

寫了這麼多了，相信你也能照葫蘆畫瓢接着往下進行回覆語音消息、視頻、音樂消息嘍，或者是再深一點的，相信本身，必定能成功，能夠大膽嘗試一下。
