Demo Code

using System;//  ww  w  .  j  a  v  a 2 s. co m
class Program
{
   public static void Main(string[] args)
   {
      Console.WriteLine("Input a series of numbers separated by commas:");
      string input = Console.ReadLine();
      char[] dividers = {',', ' '};
      string[] segments = input.Split(dividers);
      int sum = 0;
      foreach(string s in segments)
      {
         if (s.Length > 0)
         {
            if (IsAllDigits(s))
            {
               int num = 0;
               if (Int32.TryParse(s, out num))
               {
                  Console.WriteLine("Next number = {0}", num);
                  sum += num;
               }
            }
         }
      }
      Console.WriteLine("Sum = {0}", sum);
   }
   public static bool IsAllDigits(string raw)
   {
      string s = raw.Trim();
      if (s.Length == 0)
      {
         return false;
      }
      for(int index = 0; index < s.Length; index++)
      {
         if (Char.IsDigit(s[index]) == false)
