WebResponse res;
res = req.GetResponse();
StreamReader reader = new StreamReader(res.GetResponseStream());
textBox2.Text = reader.ReadToEnd();

Answer 1

If you mean Accept-Encoding, you can use Headers property of your req object just like that:

req.Headers["Accept-Encoding"] = "gzip, deflate";

But when you receive response, you need to wrap res.GetResponseStream() in GZipStream or DeflateStream if you want to read response content.
