Webclient C# 异步下载完成后获取文件路径

Question

我有这个方法：

public void downloadClip()
        {
            using (WebClient wc = new WebClient())
            {
                //Download
                wc.DownloadFileCompleted += Wc_DownloadFileCompleted;
                string file_name_ender = @"My\Path";
                wc.DownloadFileAsync(new System.Uri(@downloadUri), file_name_ender);
            }
        }

然后我有这个 DownloadFileCompleted:

private void Wc_DownloadFileCompleted(object sender, AsyncCompletedEventArgs e)
        {
            //I need to get where file was downloaded to
        }

然后我需要进入这个说明我下载文件的位置的方法字符串。基本上我的 file_name_ender.

感谢您的帮助。

使用第二种重载方法：

wc.DownloadFileAsync(uri, file_name_ender, file_name_ender);

然后就可以从事件中的UserState属性中获取值了：

private void Wc_DownloadFileCompleted(object sender, AsyncCompletedEventArgs e)
{
    var filename = (string)e.UserState;
}
