Get Response from HttpWebRequest on Windows Phone 8

Question

I'm trying to do a WebRequest to a site from a Windows Phone Application. But is vry important for me to also get the response from the server. Here is my code:

            Uri requestUri = new Uri(string.Format("http://localhost:8099/hello/{0}", metodo));
        HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create(requestUri);
        httpWebRequest.ContentType = "application/xml; charset=utf-8";
        httpWebRequest.Method = "POST";

        using (var stream = await Task.Factory.FromAsync<Stream>(httpWebRequest.BeginGetRequestStream,
                                                     httpWebRequest.EndGetRequestStream, null))
        {
            string xml = "<string xmlns=\"http://schemas.microsoft.com/2003/10/Serialization/\">Ahri</string>";

            byte[] xmlAsBytes = Encoding.UTF8.GetBytes(xml);

            await stream.WriteAsync(xmlAsBytes, 0, xmlAsBytes.Length);
        }

Unfortunatelly, I have no idea of how I could get the response from the server. Does anyone have an idea?

Thanks in advance.

Thanks to @max I found the solution and wanted to share it above. Here is how my code looks like:

            string xml = "<string xmlns=\"http://schemas.microsoft.com/2003/10/Serialization/\">Claor</string>";
        Uri requestUri = new Uri(string.Format("http://localhost:8099/hello/{0}", metodo));
        string responseFromServer = "no response";

        HttpWebRequest httpWebRequest = HttpWebRequest.Create(requestUri) as HttpWebRequest;
        httpWebRequest.ContentType = "application/xml; charset=utf-8";
        httpWebRequest.Method = "POST";



        using (Stream requestStream = await httpWebRequest.GetRequestStreamAsync())
        {
            byte[] xmlAsBytes = Encoding.UTF8.GetBytes(xml);

            await requestStream.WriteAsync(xmlAsBytes, 0, xmlAsBytes.Length);
        }

        WebResponse webResponse = await httpWebRequest.GetResponseAsync();
        using (var reader = new StreamReader(webResponse.GetResponseStream()))
        {
            responseFromServer = reader.ReadToEnd();
        }

I hope it will help someone in the future.

This is very common question for people new in windows phone app development. There are several sites which gives tutorials for the same but I would want to give small answer here.

In windows phone 8 xaml/runtime you can do it by using HttpWebRequest or a WebClient .

Basically WebClient is a wraper around HttpWebRequest .

If you have a small request to make then user HttpWebRequest. It goes like this

HttpWebRequest request = HttpWebRequest.Create(requestURI) as HttpWebRequest;
WebResponse response = await request.GetResponseAsync();
using (var reader = new StreamReader(response.GetResponseStream()))
{
    string responseContent = reader.ReadToEnd();
    // Do anything with you content. Convert it to xml, json or anything.
}

Although this is a get request and i see that you want to do a post request, you have to modify a few steps to achieve that.
