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

bool success;

//  Any string unlocks the component for the 1st 30-days.
success = zip.UnlockComponent("Anything for 30-day trial");
if (success != true) {
    textBox1.Text += zip.LastErrorText + "\r\n";
    return;
}

success = zip.NewZip("test.zip");
if (success != true) {
    textBox1.Text += zip.LastErrorText + "\r\n";
    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;
recurse = true;
success = zip.AppendFiles("c:/temp/a/*",recurse);
if (success != true) {
    textBox1.Text += zip.LastErrorText + "\r\n";
    return;
}

success = zip.WriteZipAndClose();
if (success != true) {
    textBox1.Text += zip.LastErrorText + "\r\n";
    return;
}

MessageBox.Show("Zip Created!");
