string that i encr

Answer 1

My guess is that the Delphi encryption encodes the string as an Ansi string (one byte per character) and the C# encryption encodes the string as a Unicode UTF16 string (two bytes per character). If you are using Delphi 2007 and below this is almost certainly the case.

PS The length of the encrypted string in Delphi is also a bit of a giveaway - 32 characters for a 22 character raw string implies one byte per character - this is not the case for C#.
