c＃使用Async下载多个文件

Question

我有这个代码适用于一个文件下载。

如何为此代码添加多个要下载的文件？

 private void Form1_Load(object sender, EventArgs e)
 {
     WebClient client = new WebClient();
     client.DownloadProgressChanged += Client_DownloadProgressChanged;
     client.DownloadFileCompleted += Client_DownloadFileCompleted;
     client.DownloadFileAsync(new Uri("http://download.thinkbroadband.com/10MB.zip"), @"c:\folder\10MB.zip");
 }

 private void Client_DownloadFileCompleted(object sender, AsyncCompletedEventArgs e)
 {
     MessageBox.Show("completed");
 }

 private void Client_DownloadProgressChanged(object sender, DownloadProgressChangedEventArgs e)
 {
     progressBar1.Maximum = (int)e.TotalBytesToReceive / 100;
     progressBar1.Value = (int)e.BytesReceived / 100;
 }

您可以创建多个进度条和多个Web客户端。每个WebClient都应使用适当的进度条。
