// See Global Unlock Sample for sample code.

Chilkat.Zip zip = new Chilkat.Zip();

// Intialize the zip object by calling NewZip.
bool success = zip.NewZip("qa_output/test.zip");

// Set a path prefix:
zip.PathPrefix = "directory_name/";

// Add references to files:
bool recurse = true;
success = zip.AppendFiles("c:/zipTest/directory_name/*",recurse);
if (success != true) {
    Debug.WriteLine(zip.LastErrorText);
    return;
}

success = zip.WriteZipAndClose();
if (success != true) {
    Debug.WriteLine(zip.LastErrorText);
    return;
}

Debug.WriteLine("success.");
