Request.InputStream

将数据作为XML数据发送,例如:

public   void  PostXml( string  url,  string  xml)
{ 
   byte[] bytes = Encoding.UTF8.GetBytes(xml); 
   HttpWebRequest request = (HttpWebRequest) WebRequest.Create(url); 
   request.Method = "POST"; 
   request.ContentLength = bytes.Length; 
   request.ContentType = "text/xml"; 
   using (Stream requestStream = request.GetRequestStream()) { 
     requestStream.Write(bytes, 0, bytes.Length); 
   } 

   HttpWebResponse response = (HttpWebResponse) request.GetResponse(); 
   if (response.StatusCode != HttpStatusCode.OK) { 
     string message = String.Format("POST failed. Received HTTP {0}", 
     response.StatusCode); 
     throw new ApplicationException(message); 
   } 
}

接收端通过Request.InputStream读取:

byte [] byts  =   new   byte [Request.InputStream.Length];
Request.InputStream.Read(byts, 0 ,byts.Length);
string  req  =  System.Text.Encoding.Default.GetString(byts);
req  =  Server.UrlDecode(req);

对于完整的XML数据,可以:

xmlDoc  =   new  XmlDocument();
xmlDoc.load(Request.InputStream);
