using System.DirectoryServices.AccountManagement;

using System.IO;

using System.Linq;

using System.Net;

using System.Net.Sockets;

namespace AbundantCode

{

internal class Program

{

// Function to find if the number is divisible by 2

static bool DivisibleByTwo(int Input)

{

return Input % 2 == 0;

}

// Example of Predicate Delegate in C#

private static void Main(string[] args)

{

List<int> Input = new List<int> { 1, 3, 5 , 8 , 10};

Predicate<int> PredicateDelegate = new Predicate<int>(DivisibleByTwo);

List<int> OutPut = Input.FindAll(PredicateDelegate);

foreach (var item in OutPut)

Console.WriteLine(item);

Console.ReadKey();

}

}

}
