    Hi,

    I couldn't quite catch what exactly you are trying to achieve from the provided sample.  Here a few notes that might be of help:

    1. SelectEntry is not what you want: "This Method is intended for use with a ZipFile that has been Read from storage. When creating a new ZipFile, this Method will work only after the ZipArchive has been Saved to the disk (the ZipFile class subsequently and implicitly reads the Zip archive from storage.) Calling SelectEntries on a ZipFile that has not yet been saved will deliver undefined results. " - check out its help page
    2. ArgumentNullException is kind of expected because the string SelectCriteria has a specific format and in your case it is invalid - for more info click here
    3. So instead of 
      ZipEntry en = zip.SelectEntries(FileName).FirstOrDefault();
      I suggest to use something like this: 
      ZipEntry en = zip.Entries.FirstOrDefault(e => e.FileName == FileName);

     

    Regards
