A starter question: length of an array

[calnastic]

I created an array and tried to get the length of this array, but

This is my code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication2
{
    class Program
    {
        static void Main(string[] args)
        {
            int[] arr = {1,2,3,4,5,6,7,8,9,10};
            Console.WriteLine("first dimension length", arr.Length);

        }
    }
}

This is the screenshot of the output:

Please tell me where I did wrong.
Thanks.

You forgot to add the place holder for the value.

Console.WriteLine("first dimension length {0}", arr.Length);
