Question

I need to use the following:

    using Microsoft.Deployment.Compression.Zip;

From looking online it says I need the following reference dlls

    Microsoft.Deployment.Compression.dll
    Microsoft.Deployment.Compression.Zip.dll

but I could not find these in the .NET folder.

Just as a FYI, below is how I plan to use it.

    // CREATING ZIP FILE BY ADDING LIST OF FILES
    ZipInfo zip = new ZipInfo(@"C:\testarchive1.zip");
    List<strng> files = new List<string>();
    files.Add(@"C:\test1.txt");
    files.Add(@"C:\test2.txt");
    files.Add(@"C:\test3.txt");
    zip.PackFiles(null, files, null);

    // CREATING ZIP FILE BY ADDING FOLDER (WITH SUB-FOLDERS) USING MAXIMUM COMPRESSION

     zip = new ZipInfo(@"C:\testarchive2.zip"); 

     zip.Pack(@"C:\Test", true, Microsoft.Deployment.Compression.CompressionLevel.Max, null);

Try this :

Sample code :

 using (ZipFile zip = new ZipFile())
 {
     // add this map file into the "images" directory in the zip archive
     zip.AddFile("c:\\images\\personal\\7440-N49th.png", "images");
     // add the report into a different directory in the archive
     zip.AddFile("c:\\Reports\\2008-Regional-Sales-Report.pdf", "files");
     zip.AddFile("ReadMe.txt");
     zip.Save("MyZipFile.zip");
 }

Just as easy as your example.
