WebRequest Post Xml
WebRequest request = WebRequest.Create ("http://www.contoso.com/PostAccepter.aspx ");
// Set the Method property of the request to POST.
request.Method = "POST";
// Create POST data and convert it to a byte array.
string postData = "This is a test that posts this string to a Web server.";
byte[] byteArray = Encoding.UTF8.GetBytes (postData);
// Set the ContentType property of the WebRequest.
request.ContentType = "application/x-www-form-urlencoded";
// Set the ContentLength property of the WebRequest.
request.ContentLength = byteArray.Length;
// Get the request stream.
Stream dataStream = request.GetRequestStream ();
// Write the data to the request stream.
dataStream.Write (byteArray, 0, byteArray.Length);
// Close the Stream object.
dataStream.Close ();
// Get the response.
WebResponse response = request.GetResponse ();
// Display the status.
Console.WriteLine (((HttpWebResponse)response).StatusDescription);
// Get the stream containing content returned by the server.
dataStream = response.GetResponseStream ();
// Open the stream using a StreamReader for easy access.
StreamReader reader = new StreamReader (dataStream);
// Read the content.
string responseFromServer = reader.ReadToEnd ();
// Display the content.
Console.WriteLine (responseFromServer);
// Clean up the streams.
reader.Close ();
dataStream.Close ();

Q.这是msdn 上面的一个例子,用这个方法post 一般的字符 没有问题,但是post一个xml串 如下:
System.Xml.XmlDocument xmlpostdata = new System.Xml.XmlDocument();
xmlpostdata.Load("d:\\ss\\test.xml");
string postData = xmlpostdata.InnerXml;
在 WebResponse response = request.GetResponse ();
提示错误 WebExceptionStatus ProtocolError
A.将string postData = xmlpostdata.InnerXml;
改为
string postData = HttpUtility.HtmlEncode(xmlpostData.InnerXml);
