Whether the ZipOutputStream should use case-insensitive comparisons when
checking for uniqueness of zip entries.
Declaration Syntax RemarksThough the zip specification doesn't prohibit zipfiles with duplicate entries, Sane zip files have no duplicates, and the DotNetZip library cannot create zip files with duplicate entries. If an application attempts to call PutNextEntry(String) with a name that duplicates one already used within the archive, the library will throw an Exception.
This property allows the application to specify whether the ZipOutputStream instance considers ordinal case when checking for uniqueness of zip entries.
