Demonstrates how to create a zip where the filename within the .zip is different than the filename that was added from the filesystem.

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

bool success;

success = zip.UnlockComponent("anything for 30-day trial");
if (success != true) {
    MessageBox.Show("Failed to unlock zip component");
    return;
}

//  Intialize the zip object by calling NewZip.
zip.NewZip("myZip.zip");

//  Add a reference to a file on disk to the zip object.
//  (When appending files to a zip, the files are not actually
//  read into memory.  References to the file(s) are added.
//  When WriteZip is called, the referenced files are streamed in
//  and compressed to the .zip.)
bool saveExtraPath;
saveExtraPath = false;
success = zip.AppendOneFileOrDir("c:/temp/a/hamlet.xml",saveExtraPath);
if (success != true) {
    MessageBox.Show(zip.LastErrorText);
    return;
}

//  The zip object references a single file.
//  Retrieve the entry object...
Chilkat.ZipEntry entry = null;
entry = zip.GetEntryByIndex(0);

//  Set the entry's filename to anything you want:
entry.FileName = "somethingElse.xml";

//  Note: Internally, the zip component retains the name of
//  the file referenced.  The current setting of the zip entry's
//  FileName property is stored in the .zip when writing.

//  The zip written here will contain somethingElse.xml
success = zip.WriteZipAndClose();
if (success != true) {
    MessageBox.Show(zip.LastErrorText);
}
else {
    MessageBox.Show("Zip created!");
