❔ So I've created a downloader, how do I link a progress bar to it? Winform, .NET framework

private void button1_Click(object sender, EventArgs e)
        {
            var client = new WebClient();


            try
            {
                client.DownloadFile("http://moonshroud.net/patchingtest.zip", @"patchtest.zip");
                string zipPath = @".\patchtest.zip";
                string extractPath = @".\Wrath of the Lich King";
                ZipFile.ExtractToDirectory(zipPath, extractPath);
                File.Delete(@".\Wrath of the Lich King\Data\enUS\realmlist.wtf");


                client.DownloadFile("http://moonshroud.net/World-of-Warcraft-3.3.5a.12340-enUS%20PATCH.zip", @"patch.zip");
                zipPath = @".\patch.zip";
                extractPath = @".\Wrath of the Lich King";
                ZipFile.ExtractToDirectory(zipPath, extractPath);
                File.Delete(@".\patchtest.zip");
                File.Delete(@".\patch.zip");
            }
            
            catch {}

        }
