Why in my WebClient DownloadFileAsync method downloading an Empty File?

Question

I have this C# code but the final esi.zip results in 0 length or basically empty. The URL does exist and confirms to download the file manually. I am baffled buy this.

Answer 1

 objFeedBO = new FeedBO();
 string strfilename = System.IO.Path.GetFileName(url);
 FileStream outputStream = new FileStream(DownloadPath + "\\" + strfilename, FileMode.Create);

 string targetdownloadedFile = @"D:\TestZip.php";

 WebClient myWebClient = new WebClient();
 myWebClient.DownloadFileAsync(new Uri(url), targetdownloadedFile);
 while (myWebClient.IsBusy) { }
