Downloading and saving a file Async in Windows Phone 8

Question

How can I download and save a file to IsolatedStorage asynchronously? I used WebClient first for the purpose, but I couldn\'t await till completion

Answer 1

Try something like this (not tested) :

try
{
    using (IsolatedStorageFile myIsolatedStorage = IsolatedStorageFile.GetUserStoreForApplication())
    {
        IsolatedStorageFileStream fileStream = myIsolatedStorage.CreateFile("fileNameHere");

        BitmapImage bitmap = new BitmapImage();
        var stream = await DownloadFile(new Uri("http://someuri.com", UriKind.Absolute));
        bitmap.SetSource(stream);
        WriteableBitmap wb = new WriteableBitmap(bitmap);

        // Encode WriteableBitmap object to a JPEG stream.
        Extensions.SaveJpeg(wb, fileStream, wb.PixelWidth, wb.PixelHeight, 0, 85);
        fileStream.Close();
    }
}
catch (Exception ex)
{
    //Exception handle appropriately for your app  
}
