// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

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

bool success = zip.NewZip("test.zip");
if (success != true) {
    Debug.WriteLine(zip.LastErrorText);
    return;
}

// Append a directory tree.  The call to AppendFiles does
// not read the file contents or append them to the zip
// object in memory.  It simply appends references
// to the files so that when WriteZip or WriteZipAndClose 
// is called, the referenced files are streamed and compressed
// into the .zip output file.

bool recurse = true;
success = zip.AppendFiles("c:/temp/a/*",recurse);
if (success != true) {
    Debug.WriteLine(zip.LastErrorText);
    return;
}

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

Debug.WriteLine("Zip Created!");
