I think VB.NET is an easy learning language and most functions are predefined, C#.NET is most powerful and faster than VB.NET, but we need to write some functions in C# for ourselves such as string functions.
public class Strings
public static String Right(String Str, byte Len)
String R = Str.Substring((Str.Length - Len), Len);
public static String Left(String Str, byte Len)
String L = Str.Substring(0, Len);
