How can i open an image in it's full size in UWP - image

Question

I am working on a chat app:
If the user taps on an image, it will show in full size. The following method is called:
Handle_Tapped():
void Handle_Tapped(object sender, System.EventArgs e)
{
try
{
Image image = sender as Image;
string filePath = String.Empty;
filePath = image.Source as FileImageSource;
Eva3Toolkit.CommonUtils.openImage(filePath);
}
catch (Exception ex)
{
throw ex;
}
}
Which calls (depending on the OS):
openImage() in Android:
public void openImage(string filePath)
{
Intent sendIntent = new Intent(Intent.ActionView);
sendIntent.SetDataAndType(Android.Net.Uri.Parse("file:" + filePath), "image/*");
Forms.Context.StartActivity(Intent.CreateChooser(sendIntent, "Bild öffnen..."));
}
openImage() in iOS:
public void openImage(string filePath)
{
var firstController = ((UIApplicationDelegate)(UIApplication.SharedApplication.Delegate)).Window.RootViewController.ChildViewControllers[0].ChildViewControllers[1].ChildViewControllers[0];
var navcontroller = firstController as UINavigationController;
var docIC = UIDocumentInteractionController.FromUrl(new NSUrl(filePath, true));
docIC.Delegate = new DocInteractionC(navcontroller);
docIC.PresentPreview(true);
}
Now I want to create a method openImage() in UWP, but I don't know know. I know that I will most likely have to work with the image as a StorageFile instead of the path because only a StorageFile grants me permission to open the image.
Is there a way to open the image in full size in UWP? I highly prefer to not create a new view for this.

Answer 1

A Launcher can open a file with the program that is assigned to the file:
public async void openImageAsync(string filePath)
{
StorageFile storageFile = await StorageFile.GetFileFromPathAsync(filePath);
await Launcher.LaunchFileAsync(storageFile);
}
For my situation it's working that I use filePath because the files are in a local folder.
The output looks like this:
