A common need is to unzip from an AES encrypted Zip archive directly into a string variable, such that the unencrypted file never resides on disk, even temporarily. This example shows how to do it.

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) {
    MessageBox.Show(zip.LastErrorText);
    return;
}

//  This example opens a WinZip-compatible AES encrypted
//  .zip that contains a single file: hamlet.xml.

//  It decrypts and unzips hamlet.xml directly into a string
//  variable.
zip.SetPassword("secret");
success = zip.OpenZip("hamlet.zip");
if (success != true) {
    MessageBox.Show(zip.LastErrorText);
    return;
}

Chilkat.ZipEntry entry = null;
string xmlText;

entry = zip.GetEntryByName("hamlet.xml");
if (!(entry == null )) {
    xmlText = entry.InflateToString2();
    textBox1.Text += xmlText + "\r\n";

}
else {
    MessageBox.Show("Failed to find entry in zip");
}
