如何从.NET发布SOAP请求？

我做过类似的事情,手动构建一个xml请求,然后使用webrequest对象提交请求:

string data = "the xml document to submit";
string url = "the webservice url";
string response = "the response from the server";

// build request objects to pass the data/xml to the server
byte[] buffer = Encoding.ASCII.GetBytes(data);
HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = buffer.Length;
Stream post = request.GetRequestStream();

// post data and close connection
post.Write(buffer, 0, buffer.Length);
post.Close();

// build response object
HttpWebResponse response = request.GetResponse() as HttpWebResponse;
Stream responsedata = response.GetResponseStream();
StreamReader responsereader = new StreamReader(responsedata);
response = responsereader.ReadToEnd();
