Question

I want its output as uppercase. This is what I get on Server.UrlEncode(\"http://\"):

http%3a%2f%2f

but I need:

<         


        

Answer 1

This is very easy

Regex.Replace( encodedString, @"%[a-f\d]{2}", m => m.Value.ToUpper() )

I.e. replace all hex letter-digit combinations to upper case
