我使用以下代码在画布上选择图像。现在我想在导航到另一个画布时将此图像添加到另一个画面上。
private async void edit_click(object sender, RoutedEventArgs e)
{
Windows.Storage.Pickers.FileOpenPicker filepicker = new Windows.Storage.Pickers.FileOpenPicker();
filepicker.SuggestedStartLocation = Windows.Storage.Pickers.PickerLocationId.PicturesLibrary;
filepicker.FileTypeFilter.Add(".jpg");
filepicker.FileTypeFilter.Add(".png");
filepicker.FileTypeFilter.Add(".bmp");
filepicker.ViewMode = Windows.Storage.Pickers.PickerViewMode.Thumbnail;
Windows.Storage.StorageFile imageFile = await filepicker.PickSingleFileAsync();
if (imageFile != null)
{
Windows.UI.Xaml.Media.Imaging.BitmapImage bitmap = new Windows.UI.Xaml.Media.Imaging.BitmapImage();
Windows.Storage.Streams.IRandomAccessStream stream = await imageFile.OpenAsync(Windows.Storage.FileAccessMode.Read);
Image newImage = new Image();
bitmap.SetSource(stream);
newImage.Source = bitmap;
newImage.Height = 250;
newImage.Stretch = Stretch.UniformToFill;
newImage.ManipulationMode = ManipulationModes.All;
this.theCanvas.Children.Add(newImage);
}
}
private void save_click(object sender, RoutedEventArgs e)
{
this.Frame.Navigate(typeof(showdp));
}

你可以通过多种方式做到,一个是创建一个静态的图像存储库,如:
public class Settings
{
public static Image CanvasImage;
}
并在您的代码,编辑点击或您考虑的位置设置,您可以使用以下方式从应用的任何部分进行设置:
Settings.CanvasImage = ...
