C# Deleting a .ZIP file after unzipping

Question

I am using the Ionic.Zip.dll from the DotNetZip library and I'm trying to delete the ZIP file after it finishes unzipping, but I can't manage to do it.

Here is the code I have currently:

    using (ZipFile zip = ZipFile.Read(nextVersion + ".zip"))
{
    zip.ExtractAll(Directory.GetCurrentDirectory(), ExtractExistingFileAction.OverwriteSilently);

    try
    {
        File.Delete(nextVersion + ".zip");
    }
    catch (Exception)
    {
        MessageBox.Show("Could not delete ZIP!");
        Environment.Exit(1);
    }
}

What am I doing wrong here?

Answer 1

You are getting the exception because the file is still open when you try to delete. Move the File.Delete to after the using block.

Answer 2

Try this?

try {
    using (ZipFile zip = ZipFile.Read(nextVersion + ".zip"))
    {
        zip.ExtractAll(Directory.GetCurrentDirectory(), ExtractExistingFileAction.OverwriteSilently);
    }
    File.Delete(nextVersion + ".zip");
}
catch (Exception) {
   MessageBox.Show("Could not delete ZIP!");
   Environment.Exit(1);
}
