要从指定的Url地址上下载Rss文件到本地，
 myClient.DownloadFile(Url, filePath);
怎样才能根据DownloadFile方法的下载数据进度来显是ProgressBar空键的进度呢？
请各位指教，谢谢……

怎么没一个人回复啊？

//添加myClient的DownloadProgressChanged事件
myClient.DownloadProgressChanged += new DownloadProgressChangedEventHandler(wc_DownloadProgressChanged);


        void wc_DownloadProgressChanged(object sender, DownloadProgressChangedEventArgs e)
        {
            //这就值就是你要的百分比值
            e.ProgressPercentage
        }
