asp.net微信开发（开发者接入)

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
 }

以上就是关于asp.net微信开发的第一篇，针对开发者接入进行学习，之后会有更新更多关于asp.net微信开发的文章，希望大家持续关注。
