Wait Till The Last File Is Downloaded

Solution 1:

You most certainly do not want to use WebClient.DownloadFileAsync but its newer successor WebClient.DownloadFileTaskAsync. This would be used like this:

await DLClient.DownloadFileTaskAsync(new Uri(LinkURL), @"C:\temp\" + ExtractFilename);

This is an async process, so your calling method will need to be async as well. By awaiting it, you make sure that your program continues only after the download is complete (or has failed).

Solution 2:

You should load and download it asynchronously instead of blocking the current thread. When you do this it will release the thread to the caller and return back to the context only when the Load/DownLoad has been completed

htmlDoc = await new HtmlWeb().LoadAsync(src.Attributes["href"].Value);

and

await DLClient.DownloadFileAsync(new Uri(LinkURL), @"C:\temp\" + ExtractFilename);
