How do I save a string response using HttpWebRequest on Windows Phone? - asynchronous

Question

Im trying to get the string response from this request:
void GetRequestStreamCallback(IAsyncResult asynchronousResult)
{
HttpWebRequest request = (HttpWebRequest)asynchronousResult.AsyncState;
// End the operation
Stream postStream = request.EndGetRequestStream(asynchronousResult);
string postData = "{\"email\":\"yudelsuarez#gmail.com\", \"password\":\"1234\"}";
// Convert the string into a byte array.
byte[] byteArray = Encoding.UTF8.GetBytes(postData);
// Write to the request stream.
postStream.Write(byteArray, 0, postData.Length);
postStream.Close();
// Start the asynchronous operation to get the response
request.BeginGetResponse(new AsyncCallback(GetResponseCallback), request);
}
private void GetResponseCallback(IAsyncResult asynchronousResult)
{
HttpWebRequest request = (HttpWebRequest)asynchronousResult.AsyncState;
// End the operation
HttpWebResponse response = (HttpWebResponse)request.EndGetResponse(asynchronousResult);
Stream streamResponse = response.GetResponseStream();
StreamReader streamRead = new StreamReader(streamResponse);
string responseString = streamRead.ReadToEnd();
// Close the stream object
streamResponse.Close();
streamRead.Close();
// Release the HttpWebResponse
response.Close();
}
private void Button_Click_1(object sender, RoutedEventArgs e)
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://www.tremendamuela.com/beta/index.php/api/Account");
request.ContentType = "application/json";
// Set the Method property to 'POST' to post data to the URI.
request.Method = "PUT";
// start the asynchronous operation
request.BeginGetRequestStream(new AsyncCallback(GetRequestStreamCallback), request);
}
the problem is that I dont know how to save the string....cos thats an async method it doesnt' let me modify a textBlock in the pag or save it with a StreamWriter.

Answer 1

cos thats an async method it doesnt' let me modify a textBlock in the
pag or save it with a StreamWriter.
Try:
Dispatcher.BeginInvoke(() =>
{
textBlock.Text = responseString;
});
