I\'m trying to get content of HttpResponseMessage. It should be: {\"message\":\"Action \'\' does not exist!\",\"success\":false}, but I don\'t know, how to get
{\"message\":\"Action \'\' does not exist!\",\"success\":false}
You need to call GetResponse().
Stream receiveStream = response.GetResponseStream (); StreamReader readStream = new StreamReader (receiveStream, Encoding.UTF8); txtBlock.Text = readStream.ReadToEnd();
