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);
