W 8.1异步方法和导航C＃XAML

Question

I'm trying to navigate to a page after the user click a button to download a file. The download method is async so the app wait until the method end and then navigate to the page.

Code:

private async void Button_Click(object sender, RoutedEventArgs e)
{
     await vm.DownloadFile(id);
     this.Frame.Navigate(typeof(MainPage));
}

I want to navigate to the page before the method end. How can i do this or I'm doing something wrong?

Answer 1

If you want to navigate before the download has completed, simply don't await for the download to complete before navigating:

private void Button_Click(object sender, RoutedEventArgs e)
{
     vm.DownloadFile(id);
     this.Frame.Navigate(typeof(MainPage));
}

Answer 2

Try Using This code it's the same but remove await

private async void Button_Click(object sender, RoutedEventArgs e)
{
     vm.DownloadFile(id);
     this.Frame.Navigate(typeof(MainPage));
}
