.net 微信接口（如何使用微信接口--做过的请进）
想做一个程序通过微信发信息。
有人做过吗？是怎么实现的。
-------------------------------------------------------------------
我找的参考代码，有人知道实现不步骤吗？

不是有接收用户信息么
[解决办法]
楼主的代码是用来接收的，不是发送的。
如果想通过电脑发出信息到对方手机的微信上。那么需要知道微信的通信协议和地址。否则连待接收手机的地址都不能知道，实现不了发送。另外微信的协议是加密的。
需要知道这些
[解决办法]
不管是消息推送还是消息回复都应该是xml把，我也没做过
[解决办法]
关注中，希望这个帖子有个好的结果！！
[解决办法]
前几天做这个了，
整体流程是：
1.用户发消息给微信服务器》2.微信服务器收到用户消息》3.微信服务器把消息发给你》4.你解析消息》5.返回给微信服务器》6.微信服务器发消息给用户
[解决办法]
例
/// <summary>
/// 处理文本消息
/// </summary>
/// <param name="xml"></param>
/// <returns></returns>
private static string DoTextMsg(XmlDocument xml)
{
//微信服务器发过来xml
//TODO 取出内容
string touser = xml.SelectSingleNode("xml/ToUserName").InnerText;
string fromuser = xml.SelectSingleNode("xml/FromUserName").InnerText;
//下面就是如何处理xml
xml.SelectSingleNode("xml/ToUserName").InnerText = fromuser;//设置接受消息的用户
xml.SelectSingleNode("xml/FromUserName").InnerText = touser;//消息来自谁
xml.SelectSingleNode("xml/Content").InnerText = "这是回复的内容";//这里是你回复的内容，字符串的怎么写都可以
return xml.OuterXml;//以字符串形式返回
}
公众平台接口,都是以xml形式回复,接口挂外网80端口可用,自己封装下扩展下

{
const string Token = "*****";//与那边填写的token一致
protected void Page_Load(object sender, EventArgs e)
{
string postStr = "";

{
Stream s = System.Web.HttpContext.Current.Request.InputStream;
byte[] b = new byte[s.Length];
s.Read(b, 0, (int)s.Length);
postStr = Encoding.UTF8.GetString(b);
if (!string.IsNullOrEmpty(postStr))
{
//封装请求类
