using System.Globalization;

public class Example
{
   public static void Main()
   {
      NumberFormatInfo provider = new NumberFormatInfo();
      provider.PositiveSign = "pos ";
      provider.NegativeSign = "neg ";
      provider.NumberDecimalSeparator = ".";

      object[] numericStrings = { "234", "+234", "pos 234", "234.", "255", 
                                  "256", "-1" };

      foreach (string numericString in numericStrings)
      {
         Console.Write("'{0,-8}' ->   ", numericString);
         try {
            byte number = Convert.ToByte(numericString, provider);
            Console.WriteLine(number);
         }   
         catch (FormatException) {
            Console.WriteLine("Incorrect Format");
         }                             
         catch (OverflowException) {
            Console.WriteLine("Overflows a Byte");
         }
