Question

我尝试建立一个应用程序商店，但我的下载器有问题 我尝试创建一个文件下载器，但它根本不起作用!!!而且我的视觉效果仍然告诉我我的应用程序没有任何代码错误!O认为来自OneDrive的直接链接有问题!请帮助我，代码是:

[C#]

private void btnDownload_Click(object sender, EventArgs e)
{
  WebClient webClient = new WebClient();
  webClient.DownloadFileCompleted += new AsyncCompletedEventHandler(Completed);
  webClient.DownloadProgressChanged += new DownloadProgressChangedEventHandler(ProgressChanged);
 webClient.DownloadFileAsync(new Uri(url.Text), path.Text ; )

private void ProgressChanged(object sender, DownloadProgressChangedEventArgs e)
    {
  progressBar.Value = e.ProgressPercentage;
}

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

我猜你的网址是错误的。如果您共享指向您的文件的链接，它看起来像:

https://onedrive.live.com/redir?resid=698A32FCADE8DFDA%2121825

您必须将 redir 替换为 download ，它会将文件下载到您的存储位置:

string path = @"your storage location";
string source = "https://onedrive.live.com/download?resid=698A32FCADE8DFDA%2121825";//right download url
//string source = "https://onedrive.live.com/redir?resid=698A32FCADE8DFDA%2121825";//wrong download url

WebClient webClient = new WebClient();
webClient.DownloadFileCompleted += WebClient_DownloadFileCompleted;
webClient.DownloadProgressChanged += WebClient_DownloadProgressChanged;
webClient.DownloadFileAsync(new Uri(source), path);

或者，您只需在浏览器中打开此链接，文件就会自动下载到您的下载目录:

Process.Start("https://onedrive.live.com/download?resid=698A32FCADE8DFDA%2121825");
