POST Requests on WP7

Question

I\'ve been dying for about 6 hours trying to figure out how to make a regular POST request in WP7 , I tried the answers of similar questions posted here and on many other places

Answer 1

I use this to post to facebook without any problem:

HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(requestUrl);
request.Method = "POST";
request.BeginGetResponse((e) =>
{
    try
    {
        WebResponse response = request.EndGetResponse(e);
        // Do Stuff
    }
    catch (WebException ex)
    {
        // Handle
    }
    catch (Exception ex)
    {
        // Handle
    }
}, null);

I assume you would have tried this already so it may be something to do with the post data (which isn't in the above example as facebook uses the query string). Can you give us any more info?

EDIT: This is an (untested) example for writing post data:

HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(requestUrl);
request.Method = "POST";
request.BeginGetRequestStream((e) =>
{
    using (Stream stream = request.EndGetRequestStream(e))
    {
        // Write data to the request stream
    }
    request.BeginGetResponse((callback) =>
    {
        try
        {
            WebResponse response = request.EndGetResponse(callback);
            // Do Stuff
        }
        catch (WebException ex)
        {
            // Handle
        }
        catch (Exception ex)
        {
            // Handle
        }
    }, null);
}, null);
