AddSelectedFiles Method (selectionCriteria, directoryOnDisk, recurseDirectories)

This method selects files from the the specified disk directory matching the specified selection criteria, and adds them to the ZipFile. If recurseDirectories is true, files are also selected from subdirectories.

The full directory structure in the filesystem is reproduced on the entries added to the zip archive. If you don't want this behavior, use one of the overloads of this method that allows the specification of a directoryInArchive.

For details on the syntax for the selectionCriteria parameter, see AddSelectedFiles(String).

This example zips up all *.csv files in the "files" directory, or any subdirectory, that have been saved since 2009 February 14th.

CopyC#

using (ZipFile zip = new ZipFile())
{
    // Use a compound expression in the selectionCriteria string.
    zip.AddSelectedFiles("name = *.csv  and  mtime > 2009-02-14", "files", true);
    zip.Save(PathToZipArchive);
}

CopyVB.NET

Using zip As ZipFile = New ZipFile()
    ' Use a compound expression in the selectionCriteria string.
    zip.AddSelectedFiles("name = *.csv  and  mtime > 2009-02-14", "files", true)
    zip.Save(PathToZipArchive)
End Using

This example zips up all files in the current working directory, and all its child directories, except those in the excludethis subdirectory.

CopyVB.NET

Using Zip As ZipFile = New ZipFile(zipfile)
  Zip.AddSelectedFfiles("name != 'excludethis\*.*'", datapath, True)
  Zip.Save()
End Using
