C# program to find Sum of first n Even Natural Numbers

Program

using System;
namespace SumOfNEvenNumbers
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.Write("Enter the value of n:\t");
            int n = int.Parse(Console.ReadLine());
            int i, evenSum = 0;                    
            for(i = 1; i <= n; i++)
	        {
                if((i % 2) == 0)
                {
                    evenSum += i;                    
                }
            }
            Console.WriteLine("Sum of even numbers from 1 to {0} is {1}\t", n, evenSum);
        }
    }
}

Output

Enter the value of n:   15
Sum of even numbers from 1 to 15 is 56
