How to replace %23 with # in URL?

Question

Programming

Hello, I am using the xNet library to work with requests.
The problem is that:
- The program makes a GET request and is redirected to /wall84639214_41572 # post84639214_41572
- And the program is redirected to /wall84639214_41572 %23 post84639214_41572
The # sign given in the redirect links itself is replaced by %23
What could be the problem?

Answer 1

It is replaced with %23, not %. Encoding/converting to url.

Answer 2

So it's okay! All browsers replace! Read about url encode/decode.
Functions in c#

System.Web.HttpUtility.UrlEncode("#");   //%23
System.Web.HttpUtility.UrlDecode("%23"); //#

Answer 3

var sbl = new StringBuilder("path");
sbl.AppendFormat("#");
sbl.AppendFormat("path");
sbl.ToString();
