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");
