Take a look at this library: http://www.icsharpcode.net/OpenSource/SharpZipLib/

It is pretty comprehensive, it deals with many formats, is open-source, and you can use in closed-source commercial applications.

It is very simple to use:

byte[] data1 = new byte[...];
byte[] data2 = new byte[...];
/*...*/

var path = @"c:\test.zip";
var zip = new ZipOutputStream(new FileStream(path, FileMode.Create))
            {
                IsStreamOwner = true
            }

zip.PutNextEntry("File1.txt");
zip.Write(data1, 0, data1.Length);

zip.PutNextEntry("File2.txt");
zip.Write(data2, 0, data2.Length);

zip.Close();
zip.Dispose();
