如何才有可能终止这种方法/下载功能？

private void Download_Click(object sender, EventArgs e)
{
    WebClient webClient = new WebClient();
    webClient.DownloadFileCompleted += new AsyncCompletedEventHandler(Completed);
    webClient.DownloadProgressChanged += new DownloadProgressChangedEventHandler(ProgressChanged);
