Answer 1

Simple zip file with flat structure:

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

private static void CreateZipFile(IEnumerable files, string archiveName)
{
    using (var stream = File.OpenWrite(archiveName))
    using (ZipArchive archive = new ZipArchive(stream, System.IO.Compression.ZipArchiveMode.Create))
    {
         foreach (var item in files)
         {
             archive.CreateEntryFromFile(item.FullName, item.Name, CompressionLevel.Optimal);                       
         }
     }
}

You need to add reference to System.IO.Compression and System.IO.Compression.FileSystem
