Non-Static field

Question

Vreau sa fac un auto-updater, dar am problema asta: "An Object reference is required for the non-static field", si daca in pun non-static am aceasi problema dar altundeva:

code:

        public static void Updateing()
        {
            WebClient client = new WebClient();
            client.DownloadProgressChanged += Client_DownloadProgressChanged; //a doua eroare daca il fac non-static
            client.DownloadFileCompleted += Client_DownloadFileCompleted;
     FileLink"), "fileName");
        }

        private static void Client_DownloadFileCompleted(object sender, System.ComponentModel.AsyncCompletedEventArgs e)
        {
            MessageBox.Show("Download Complete");
        }

        private static void Client_DownloadProgressChanged(object sender, DownloadProgressChangedEventArgs e)
        {
            UpdateProgress.Maximum = e.TotalBytesToReceive; //Prima eroare!
        }
