How to show message after all webClient.DownloadFileAsync completed?

Question

.NET

There are several webClients that run in a loop like this:

WebClient webClient = new WebClient();
webClient.DownloadFileCompleted += new AsyncCompletedEventHandler((sender, e) => download_completed(sender, e, id, size));
webClient.DownloadFileAsync(new Uri(url_load), filename);

How to track that all asynchronous downloads have completed?
Thanks in advance for your reply!

Answer 1

Why not decrement the counter of remaining downloads in download_completed and wait until it becomes zero?
