Array.Copy should do this for you:

          byte[] Values = new Byte[4] { 0,49,50,51 };
          byte[] Values2 = new Byte[2];
          Array.Copy( Values,1,Values2,0,2);
         Console.Write ( System.Text.Encoding.Default.GetString(Values2,0,2));

>I have an array of bytes: System.Byte[] myByteArray = new System.Byte[300];
