you can use ZipArchive Class to create zip file include asyoulik3.txt and alice29.txt :

using System;
using System.IO;
using System.Text;
using System.IO.Compression;

namespace ConvertMultipleFilesIntoZip
{
    internal class Program
    {   
        static void Main(string[] args)
       {
            using (ZipArchive archive = ZipFile.Open("compressed_files.zip", ZipArchiveMode.Create))
            {

                archive.CreateEntryFromFile("asyoulik3.txt", "asyoulik3.txt");
                archive.CreateEntryFromFile("alice29.txt", "alice29.txt");
            }
        }
    }
}
