Iterate over Matching Filenames

See more Zip Examples

Iterates over files within a .zip that match a pattern. In this case, the pattern is "*.pem". This example will open a .zip containing files of type .txt, .cer, .pem, and possibly others, and will iterate over only the .pem files. C#

bool success = false;

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

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

// Open a .zip containing PEM files, among other things..
success = zip.OpenZip("qa_data/certs/thawte-roots.zip");
if (success == false) {
    Debug.WriteLine(zip.LastErrorText);
    return;
}

Chilkat.ZipEntry entry = new Chilkat.ZipEntry();
string pemStr;
string pattern = "*.pem";

bool bHasMoreMatches = zip.EntryMatching(pattern,entry);
while (bHasMoreMatches == true) {

    Debug.WriteLine("Entry: " + entry.FileName);

    // Get the uncommpressed contents of the entry:
    pemStr = entry.UnzipToString(0,"utf-8");
    Debug.WriteLine(pemStr);

    bHasMoreMatches = entry.GetNextMatch(pattern);
