I'm using HttpUtility.UrlEncode to turn parameter value which concluds '+' to safe string deliverd among pages, so it turns '+' into %2b, but when I use Decode method it give me back a space. Why?

HttpServerUtility. UrlEncode Method (System. Web) Encodes a string for reliable HTTP transmission from the Web server to a client through the URL.
URLs cannot contain spaces. URL encoding normally replaces a space with a plus (+) sign or with %20.
URLDECODE is a string manipulation function that manipulates CHARACTER string data.
This is a type of encoding-decoding approach where the built-in PHP functions urlencode() and urldecode()are implemented to encode and decode the URL, respectively. This encoding will replace almost all the special characters other than (_), (-), and (.) in the given URL.
Decoding %2b would give you back a +, but decoding a + would give you back a space.
So, most likely your string is decoded twice. If you are reading it from the Request.Querystring collection, then it's already decoded, so you shouldn't decode it again.
