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?

try deleting the file outside your using statement. There may still be a lock on the file. — Brian, Jul 05 '11 at 02:19
Is the ZIP file still in use? Should you close the file before trying to delete? — Brad, Jul 05 '11 at 02:20

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.

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);
}

Yes! I have the same answer as Richard Schneider. The zip file is still accessed by current thread, you have to close it first.

Try this

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

Move File.Delete outside using brackets using (ZipFile zip = ZipFile.Read(nextVersion + ".zip"))
