HTTP Post of XML in Windows Forms

Question

Can someone please give me a working example of how I can post an xml document/string to a url listening to the request in Windows Forms? I have the following but have the feeling that i am going down the wrong path: MSXML2.XMLHTTPClass httpRequest = new MSXML2.XMLHTTPClass(); httpRequest.open("OPEN",URL,"False","",""); httpRequest.send(URL); Thanks in advance to all replies!
