Whether the download can be resumed from where the last download was not completed about downloader HOT 3 CLOSED

Hi everybody,
First, make sure you set false to the ClearPackageOnCompletionWithFailure option. Because, this option tells the Downloader to clear the package and downloaded data when the download is completed with failure, but the default value is false.

Second, before downloading, keep the downloadService.Package in a variable;

// At first, keep and store the Package file to resume 
// your download from the last download position:
DownloadPackage pack = downloader.Package;

after downloading, you can stop or pause a download or the download may be completed with an error. Therefore, when you want to resume downloading at last point, just pass the package to the downloader like this:

await downloader.DownloadFileTaskAsync(pack);

Note: Sometimes a server does not support downloading in a specific range. That time, we can't resume downloads after canceling. So, the downloader starts from the beginning.

Additional info for saved your Packed, you can use json file for this:

public void SavedPacked(DownloadPackage packet, string rutaArchivo) { string json = JsonConvert.SerializeObject(packet); File.WriteAllText(rutaArchivo, json); }

public DownloadPackage ReadPacked(string rutaArchivo) { string json = File.ReadAllText(rutaArchivo); return JsonConvert.DeserializeObject<DownloadPackage>(json); }

if (File.Exists("your path .json file")) { var packed = LeerPacked("your path .json file"); Console.WriteLine("!---- OnResume ----!"); downloader.DownloadFileTaskAsync(packed); } else { Console.WriteLine("!---- OnStart ----!"); downloader.DownloadFileTaskAsync("url file to download", " your file name"); }

Use SavePacked in dDownloadProgressChanged
