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

string outDir = "c:/temp/testUnzipDir";

// Make sure our output directory exists.
Chilkat.FileAccess fac = new Chilkat.FileAccess();
bool success = fac.DirEnsureExists(outDir);
if (success == false) {
    Debug.WriteLine(fac.LastErrorText);
    return;
}

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

// In this example, the xml_files.zip contains some files in the subdirectories "dir1" and also "dir2/dir3".

// a1.xml
// b1.xml
// c1.xml
// dir1/a2.xml
// dir1/c2.xml
// dir2/dir3/c3.xml

success = zip.OpenZip("qa_data/zips/xml_files.zip");
if (success != true) {
    Debug.WriteLine(zip.LastErrorText);
    return;
}

// Unzip all files into the directory c:/temp/testUnzipDir
int numUnzipped = zip.UnzipInto(outDir);
if (numUnzipped < 0) {
    Debug.WriteLine(zip.LastErrorText);
    return;
}

Debug.WriteLine("Num unzipped = " + Convert.ToString(numUnzipped));

// After unzipping via UnzipInto, we have this:

// c:\temp\testUnzipDir\a1.xml
// c:\temp\testUnzipDir\b1.xml
// c:\temp\testUnzipDir\c1.xml
// c:\temp\testUnzipDir\a2.xml
// c:\temp\testUnzipDir\c2.xml
// c:\temp\testUnzipDir\c3.xml

zip.CloseZip();

Debug.WriteLine("Success.");
