    One of the things that programmers coming from Basic language variant to
a C language variant have trouble with is that Basic imposes a completely
unnecessary distinction between numbers & characters, which C (and C++ and
C#) does not. So, the following code will print " A, 66":

public class MyClass
{
 public static void Main()
 {
    Char c =(Char) 65;
  int i = 'B';
  Console.WriteLine("{0}, {1}", c, i);
 }
}

Note that the cast it required to convert 65 to a character, but not to
convert 'B' into an int.

    So, with the above in mind, you can create Tab as a character simply by:

    char csKeyTab = (char) 9;

    However, you'll probably want them as string (and for vbCrLf, it would
have to be), inwhich case you can use the predefined "escape codes":

    string csCrLf = "\r\n";
    string csKeyTab = "\t";

    But say you want a string containing a special character which doesn't
have a predefined code? This can be done also, but you'll have to translate
the ASCII code into Hexadecimal.

    string csABC = "\x41\x42\x43"; // "ABC" "A" = ASCII 65 (dec) = 41
(hex)
