我想你的网址是错的。如果您共享指向您文件的链接，它看起来像：

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

您必须通过download替换redir ，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);

作为替代方案，您只需在浏览器中打开此链接，该文件将自动下载到您的下载目录：

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

I guess your url is wrong. If you share a link to your file it looks like:

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

You have to replace the redir by download and it will download the file to your storage location:

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);

As an alternative you can simply open this link in your browser and the file will be automatically downloaded to your download directory:

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