這是文件選取器的代碼
我需要複製用戶將其打開到應用程序文件夾的圖像。 任何人都可以幫我請如何將圖片從文件夾複製到應用程序文件夾窗口存儲應用程序
private async void Button_Click(object sender, RoutedEventArgs e)
{
if (Windows.UI.ViewManagement.ApplicationView.Value != Windows.UI.ViewManagement.ApplicationViewState.Snapped ||
Windows.UI.ViewManagement.ApplicationView.TryUnsnap() == true)
{
Windows.Storage.Pickers.FileOpenPicker openPicker = new Windows.Storage.Pickers.FileOpenPicker();
openPicker.SuggestedStartLocation = Windows.Storage.Pickers.PickerLocationId.PicturesLibrary;
openPicker.ViewMode = Windows.Storage.Pickers.PickerViewMode.Thumbnail;
// Filter to include a sample subset of file types.
openPicker.FileTypeFilter.Clear();
openPicker.FileTypeFilter.Add(".bmp");
openPicker.FileTypeFilter.Add(".png");
openPicker.FileTypeFilter.Add(".jpeg");
openPicker.FileTypeFilter.Add(".jpg");
//打開文件選取器。
Windows.Storage.StorageFile file = await openPicker.PickSingleFileAsync();
// file is null if user cancels the file picker.
if (file != null)
{
// Open a stream for the selected file.
Windows.Storage.Streams.IRandomAccessStream fileStream =
await file.OpenAsync(Windows.Storage.FileAccessMode.Read);
//設置圖像源選擇bitmap.`
Windows.UI.Xaml.Media.Imaging.BitmapImage bitmapImage =
new Windows.UI.Xaml.Media.Imaging.BitmapImage();
bitmapImage.SetSource(fileStream);
img.Source = bitmapImage;
this.DataContext = file;
}
}
}
感謝
