The UrlEncode function is used to escape especial characters like '&' and '=' so a parser doesn't consider them as syntax. It takes a string (media type text/plain) and returns a string (media type application/x-www-form-urlencoded).

Encoding.UTF8.GetBytes is used to convert the string (media type application/x-www-form-urlencoded in our case) into an array of bytes, which is what the WebRequest API expects.

For Url Enoding/Decoding you need to use WebUtily class.

To see its details visit: MSDN WebUtility Class[^]
Here check UrlDecode and UrlEncode.

But from what you ask in order to get the parameters that use you should use Request.Querystring. MSDN Request.Querystring[^]
An example usage;

C#

if (Request.QueryString["id"] != null) {
            try
            {
                id = int.Parse(Request.QueryString["id"]);
            }
            catch
            {
                // deal with it
            }
        }

Good luck,
