download icons to local using c# webclient: The DownloadFileAsync/DownloadFileCompleted members of WebClient use the Event-based Asynchronous Pattern. If you want to use async and await, you should be using the Task-based Asynchronous Pattern. In this case, you should use the DownloadFileTaskAsync member, as such(Please note that your Context.listOfLocalDirectories.Add and Errors.printError methods should be threadsafe.):
private async Task DownloadFileAsync(DocumentObject doc)
{
try
{
using (WebClient webClient = new WebClient())
{
string downloadToDirectory = @Resources.defaultDirectory + value.docName;
webClient.Credentials = System.Net.CredentialCache.DefaultNetworkCredentials;
await webClient.DownloadFileTaskAsync(new Uri(value.docUrl), @downloadToDirectory);
//Add them to the local
Context.listOfLocalDirectories.Add(downloadToDirectory);
}
}
catch (Exception)
{
Errors.printError("Failed to download File: " + value.docName);
}
}
private async Task DownloadMultipleFilesAsync(List doclist)
{
await Task.WhenAll(doclist.Select(doc => DownloadFileAsync(doc)));
}
