create c# like classes in delphi

[noeska]

In C# you have special classes like String that work like this

String MyString = "    This is an test string   ";
Console.WriteLine(MyString.Trim());

It class like the String class is created like this:

Is it possible to use something like this in Delphi ((win32) 2005/turbo)? I now something like this is possible for arrays. E.g. MyObject[i] instead of MyObject.Lines[i].

Thanks for your answers in advance.
