Hello,

I need to get some information from a website

"http://www.tsetmc.com/Loader.aspx?ParTree=15"

I used any code like:

HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create("http://www.tsetmc.com/Loader.aspx?ParTree=15");
            myRequest.Method = "GET";
            WebResponse myResponse = myRequest.GetResponse();
            StreamReader sr = new StreamReader(myResponse.GetResponseStream(), System.Text.Encoding.UTF8);
            string result = sr.ReadToEnd();
            sr.Close();
            myResponse.Close();
            Console.WriteLine(result.ToString());

but the result is like :
� MI�T ��}[s����{���nHV@��R�V�8���]��ʦjkK5$Aq��wf$Kɗ�OJ*�~�>{(ӶJT���c(�}�d�i 3 b(R#�E
