Help with translating a PHP method to C#

[anu]

Can anyone help? I have a PHP method that sends an http post:\[code\]<?php// API URL$api_url = "url_of_the_API ";// Apache auth$api_user = "user";$api_pass = "pass";// Request$xml = "";$context = stream_context_create(array ('http' => array('method' => 'POST','header' => sprintf("Authorization: Basic %s\r\n",base64_encode($api_user.':'.$api_pass))."Content-type: application/x-www-form-urlencoded\r\n",'content' => http_build_query(array('xml' => $xml)),'timeout' => 5,),));$response = file_get_contents($api_url,false,$context);header ("Content-Type:text/xml");echo $response;?>\[/code\]I need to translate this to C# and I am getting a reply back from the webservice saying "POST call with XML required". I am being told that:\[code\]"the XML is not being sent via POST in the 'xml' (name) variable? This is a similar process to submitting a webform with one variable called 'xml'."\[/code\]Below is my C#\[code\] // this is where we will send it const string uri = "theUri"; // create a request var request = (HttpWebRequest) WebRequest.Create(uri); request.KeepAlive = false; request.ProtocolVersion = HttpVersion.Version10; request.Method = "POST"; request.Credentials = new NetworkCredential("theUserName", "thePassword"); // turn our request string into a byte stream var postBytes = Encoding.ASCII.GetBytes(postData); // this is important - make sure you specify type this way request.ContentType = "application/x-www-form-urlencoded"; request.ContentLength = postBytes.Length; var requestStream = request.GetRequestStream(); // now send it requestStream.Write(postBytes, 0, postBytes.Length); requestStream.Close(); // grab te response and print it out to the console along with the status code var response = (HttpWebResponse)request.GetResponse(); Console.WriteLine(new StreamReader(response.GetResponseStream()).ReadToEnd()); Console.WriteLine(response.StatusCode);\[/code\]
