var picker = new FileOpenPicker(); picker.ViewMode = PickerViewMode.Thumbnail; picker.SuggestedStartLocation = PickerLocationId.PicturesLibrary; picker.FileTypeFilter.Add(".png"); picker.FileTypeFilter.Add(".jpeg"); picker.PickMultipleFilesAndContinue();
async void OnPickMultipleFilesAndContinue(IContinuationActivatedEventArgs args) { FileOpenPickerContinuationEventArgs continuationArgs = args as FileOpenPickerContinuationEventArgs; if (continuationArgs.Files.Count > 0) { foreach (StorageFile file in continuationArgs.Files) { // Process each file } } }In this example, the OnPickMultipleFilesAndContinue method is used to handle the continuation of the file picker operation. The IContinuationActivatedEventArgs parameter is passed in, and the method checks if any files were picked by the user. If files are found, the method processes each one.
