Code: Select all

                WebClient wc = new WebClient();
                string str;

                var Url = "http://dev01.tnomer.ru:7000/private/api/dictionary/work/asd";
                wc.Encoding = Encoding.UTF8;
                wc.Headers.Set("Content-Type", "application/json");

                str = wc.DownloadString(Url );
                System.Windows.MessageBox.Show("ok" + str);
            catch (Exception ex)

                System.Windows.MessageBox.Show("error!!! " + ex.ToString());

In emulator

error!!! System.Net.WebException: The remote server returned an error: (400) Bad Request.
