Question

I am actually wondering why when I create a zip file, and I download it just after, I can’t open it because it’s broken ..

This is the code I am actually using .

        string url = ((LinkButton)sender).Tag;
        var downloadFileName = string.Format(((LinkButton)sender).ID + ".zip");
        System.IO.DirectoryInfo di = new System.IO.DirectoryInfo("C://inetpub//wwwroot//Files//Wireframes//" + url);

        using (ZipFile zip = new ZipFile())
        {
            zip.AddEntry("C://inetpub//wwwroot//Files//Wireframes//" + url, zip.Name);
            zip.AddDirectory("C://inetpub//wwwroot//Files//Wireframes//" + url);
            zip.Save(downloadFileName);
        }


        Response.ContentType = "application/zip";
        Response.AddHeader("Content-Disposition", "filename=" + downloadFileName);

Also, I am adding directly all the directories with their files inside.

You are not sending the actual data.

Response.ContentType = "application/zip";
Response.AddHeader("Content-Disposition", "filename=" + downloadFileName);
Response.TransmitFile(downloadFileName);
Response.End();
