c# - Downloading multiple images to cache in Xamarin

Question

I have an app in Xamarin in which I display images like this:

webImage.Source = new UriImageSource {
Uri = new Uri("https://xamarin.com/content/images/pages/forms/example-app.png"),
CachingEnabled = true,
CacheValidity = new TimeSpan(5,0,0,0) };

This works great - however, I now need let the user download all the images to cache with one button click, and I can't find anything on the internet.

Is it even possible with cache like this?
