Passing XML document as an parameter to Web services in C#

Question

I have to sent the XML document as an parameter to request an WebRequest from the Service using the Post method.

Can anyone help be about how to sent the XML document as an parameter, or how to get the whole document in the string to pass as in as Document.

Answer 1

If you want to POST your Xml data using a named form parameter you need to do something like this:

HttpWebRequest request = HttpWebRequest.Create("http://yourdomain.com/whatever") as HttpWebRequest;
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";

Encoding e = Encoding.GetEncoding("iso-8859-1");
XmlDocument doc = new XmlDocument();
doc.LoadXml("<foo><bar>baz</bar></foo>");
string rawXml = doc.OuterXml;

// you need to encode your Xml before you assign it to your parameter
// the POST parameter name is myxmldata
string requestText = string.Format("myxmldata={0}", HttpUtility.UrlEncode(rawXml, e));

Stream requestStream = request.GetRequestStream();
StreamWriter requestWriter = new StreamWriter(requestStream, e);
requestWriter.Write(requestText);
requestWriter.Close();
