how to avoid [Content_Types].xml in .net's ZipPackage class

Question

I wish to know if there is any way to avoid to have a [Content_Types].xml file inside the zip file while using .net\'s ZipPackage

Run this function when you finish packing your zip file:

public static void Remove_Content_Types_FromZip(string zipFileName)
    {
        string contents;
        using (ZipFile zipFile = new ZipFile(File.Open(zipFileName, FileMode.Open)))
        {
            /*
            ZipEntry startPartEntry = zipFile.GetEntry("[Content_Types].xml");
            using (StreamReader reader = new StreamReader(zipFile.GetInputStream(startPartEntry)))
            {
                contents = reader.ReadToEnd();
            }
            XElement contentTypes = XElement.Parse(contents);
            XNamespace xs = contentTypes.GetDefaultNamespace();
            XElement newDefExt = new XElement(xs + "Default", new XAttribute("Extension", "sab"), new XAttribute("ContentType", @"application/binary; modeler=Acis; version=18.0.2application/binary; modeler=Acis; version=18.0.2"));
            contentTypes.Add(newDefExt);
            contentTypes.Save("[Content_Types].xml");
            zipFile.BeginUpdate();
            zipFile.Add("[Content_Types].xml");
            zipFile.CommitUpdate();
            File.Delete("[Content_Types].xml");
            */
            zipFile.BeginUpdate();
            try
            {
                zipFile.Delete("[Content_Types].xml");
                zipFile.CommitUpdate();
            }
            catch{}
        }
    }
