        static void Main(string[] args)
        {
            string str = "1";
            int? IntNullable;
            int i;
            if (Int32.TryParse(str, out i))
            {
                IntNullable = i;
            }
            else
            {
                IntNullable = null;
            }
            Console.WriteLine(IntNullable);
            Console.ReadLine();
        }
