.NET框架提供有专门的委托类EventHandler,原型如下:public delegate void EventHandler(object sender, EventArgs e);该委托带有两个参数:一个是事件源sender,一个是不包含任何事件数据的e。e是事件参数EventArgs类。可以从EventArgs派生自己的事件参数类,对消息打包。

如果远程服务器的default.aspx中设置函数void Page_Load(object sender, EventArgs e) { String echostr = Request.QueryString["echostr"]; Response.Write(echostr); }那么使用它不能完成微信公众号与远程服务器的绑定
