C# Method like Base64String, but only alphanumeric (no plus or slash)

Question

is there any C# method that works similar to Convert.ToBase64String but doesn\'t generate anything except alphanumeric output?

Thanks!

Answer 1

A common variant of base-64 (for use on query-string) is to use '-' and '_' in place of '+' and '/'. Perhaps a bit of Replace(...) at each end would do the job?
