using System.Text;
using System.Threading.Tasks;

namespace ConsoleApp1
{
class Program
    {
static void Main(string[] args)
        {
//create an array Num of type int
int[] Num = { 1, 2, 3, 4, 5, 6, 7, 8, 9 };

Console.WriteLine("Find the count of the elements:");
/*to find the number of values in Num array will apply
 the 'count' function on the array Num*/
int Count = Num.Count();
/*print the value of 'Count' variable which is type of int
 with the helplp of WriteLine function*/
Console.WriteLine("The Count is {0}", Count);
Console.ReadLine();
        }
