is there any C# method that works similar to Convert.ToBase64String but doesn\'t generate anything except alphanumeric output?
Thanks!
You're probably looking at using something like Base32 encoding then. There is a Base32 encoder/decoder for C# here by Michael Giagnocavo. It uses a combination of capitalized letters and numbers.
There's also a related discussion on StackOverflow here.
EDIT: And if by any chance this is for URL-safe related Base64 encoding, just do Base64 and replace "+" with "-" and "/" with "_". But I'm guessing, you may not want it for that.
