Write a program in C# Sharp to shows how the three parts of a query operation execute

using System;
using System.Linq;
class LinqExercise1
{        
    static void Main()
    {
        //  The first part is Data source.
        int[] n1 = new int[10] { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 };
        Console.Write("\nBasic structure of LINQ : "); 
        Console.Write("\n---------------------------");
        // The second part is Query creation.
        // nQuery is an IEnumerable<int>
        var nQuery =
            from VrNum in n1
            where (VrNum % 2) == 0
            select VrNum;
        // The third part is Query execution.        
        Console.Write("\nThe numbers which produce the remainder 0 after divided by 2 are : \n");
        foreach (int VrNum in nQuery)
        {
            Console.Write("{0} ", VrNum);
        }
         Console.Write("\n\n");
    }
}
