protected string sendPicTextMessage(Msg _mode, string title, string description, string picurl, string url) { string res = string .Format( @"<xml> <ToUserName><![CDATA[{0}]]></ToUserName> <FromUserName><![CDATA[{1}]]></FromUserName> <CreateTime>{2}</CreateTime> <MsgType><![CDATA[news]]></MsgType> <ArticleCount>1</ArticleCount> <Articles> <item> <Title><![CDATA[{3}]]></Title> <Description><![CDATA[{4}]]></Description> <PicUrl><![CDATA[{5}]]></PicUrl> <Url><![CDATA[{6}]]></Url> </item> </Articles> </xml> " , _mode.FromUserName, _mode.ToUserName, DateTime.Now,title, description, picurl, url); return res; } |
