05. Sum Even Numbers

using System;
using System.Linq;

namespace SumEvenNumbers
{
    class Program
    {
        static void Main(string[] args)
        {
            int[] num = Console.ReadLine()
                .Split()
                .Select(int.Parse)
                .ToArray();
            int sum = 0;

            for (int i = 0; i < num.Length; i++)
            {
                int current = num [i];
                if (current % 2 == 0)
                {
                    sum += current;
                }
            }
            Console.WriteLine(sum);
        }
    }
}


Pешение с LINQ:

using System;
using System.Linq;

namespace SumEvenNumbers
{
    class Program
    {
        static void Main(string[] args)
        {
            int[] num = Console.ReadLine()
                .Split()
                .Select(int.Parse)
                .Where( a => a % 2 == 0)
                .ToArray();

            Console.WriteLine(num.Sum());
        }
    }
}


ИЛИ :

using System;
using System.Linq;

namespace SumEvenNumbers
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine(Console.ReadLine().Split().Select(int.Parse).Where(a => a % 2 == 0).Sum());
        }
    }
}
