asp.net微信开发开发者接入技巧

先上图，看一看需要进行哪些项目的操作：

在项目的根目录或者特定的文件夹内，创建一个ashx文件(一般处理程序文件)，如图

 public void ProcessRequest(HttpContext context) {  context.Response.ContentType = "text/plain";    string postString = string.Empty;  if (HttpContext.Current.Request.HttpMethod.ToUpper() == "POST")  {  using (Stream stream = HttpContext.Current.Request.InputStream)  {   Byte[] postBytes = new Byte[stream.Length];   stream.Read(postBytes, 0, (Int32)stream.Length);   postString = Encoding.UTF8.GetString(postBytes);  }  if (!string.IsNullOrEmpty(postString))  {   ResponseXML(postString);//返回给微信用户信息  }  ///加载自定义菜单  string postData = "{" + "/r/n";
