Left, Right and Mid String Functions for C#

Unlike Visual Basic, C# doesn't have built-in string methods to extract parts of string from the Left, Right or a location specified through Mid. Unfortunately you have to create the logic yourself.

Here are examples of Left, Right and Mid in C# with the use of the Substring method present in C# (and VB):

class LeftRightMid
      static void Main(string[] args)
         string myString = "This is a string";
         //Get 4 characters starting from the left
         //Get 6 characters starting from the right
         //Get 4 characters starting at index 5 of the string
      public static string Left(string param, int length)
         string result = param.Substring(0, length);
         return result;
      public static string Right(string param, int length)
         string result = param.Substring(param.Length - length, length);
         return result;
      public static string Mid(string param,int startIndex, int length)
         string result = param.Substring(startIndex, length);
         return result;
