With the release of the .NET Framework 4.5 this is actually a lot easier now with the updates to System.IO.Compression which adds the ZipFile class. There is a good walk-through on codeguru; however, the basics are in line with the following example:

using System.Collections.Generic;
using System.IO;
using System.IO.Compression;
using System.IO.Compression.FileSystem;

namespace ZipFileCreator
{
    public static class ZipFileCreator
    {
        /// 

        /// Create a ZIP file of the files provided.
        /// 
        /// The full path and name to store the ZIP file at.
        /// The list of files to be added.
        public static void CreateZipFile(string fileName, IEnumerable files)
        {
            // Create and open a new ZIP file
            var zip = ZipFile.Open(fileName, ZipArchiveMode.Create);
            foreach (var file in files)
            {
                // Add the entry for each file
                zip.CreateEntryFromFile(file, Path.GetFileName(file), CompressionLevel.Optimal);
            }
            // Dispose of the object when we are done
            zip.Dispose();
        }
    }
}
