        string[] stringOfInteger = { "1", "5", "10", "15", null, "", "20", "25", "30" };


        //create an integer data type array.
        int[] intArray = (from x in stringOfInteger
                         where x != "" && x!= null
                         select int.Parse(x)).ToArray();

        Console.WriteLine("elements of int array............");
        foreach (int x in intArray)
        {
            Console.WriteLine("{0}  => {1}",x, x.GetType());
        }
