如何将图像或文件在任何位置复制或删除到UWP应用程序中的文件夹中

太谢谢你了 我找到了解决方案，您的回答很有用。

这是解决方案

这是上传按钮图片

        private async void BtnAddImage_OnClick(object sender, RoutedEventArgs e)
    {
        var imagePicker = new FileOpenPicker
        {
            ViewMode = PickerViewMode.Thumbnail,
            SuggestedStartLocation = PickerLocationId.Desktop,
            FileTypeFilter = { ".jpg", ".png", ".bmp", ".gif", ".tif" }
        };


        var imageFile = await imagePicker.PickSingleFileAsync();
        if (imageFile == null)
        {
            return;
        }

        _storageFile = imageFile;
        _path = imageFile.Path;

        var dataPackage = new DataPackage();

        dataPackage.SetBitmap(RandomAccessStreamReference.CreateFromFile(imageFile));
        Clipboard.SetContent(dataPackage);




        var dataPackageView = Clipboard.GetContent();
        if (!dataPackageView.Contains(StandardDataFormats.Bitmap)) return;


        IRandomAccessStreamReference imageReceived = await dataPackageView.GetBitmapAsync();


        if (imageReceived == null) return;
        using (var imageStream = await imageReceived.OpenReadAsync())
        {
            var bitmapImage = new BitmapImage();
            bitmapImage.SetSource(imageStream);
            ImgSupplier.Source = bitmapImage;

        }

        StorageApplicationPermissions.FutureAccessList.Add(imageFile);
    }

重新运行路径

    private static string GetPath(string folderName)
    {

  var root = Windows.ApplicationModel.Package.Current.InstalledLocation.Path + @"\Assets\";

        var fullPath = Path.Combine(root, folderName);
        return fullPath;
    }

这是一个保存按钮

    private StorageFile _storageFile;   
    private async void BtnAddExpenditure_OnClick(object sender, RoutedEventArgs e)
    {
        var getPath = GetPath("Companies");

        var folder = await StorageFolder.GetFolderFromPathAsync(getPath);
        await _storageFile.CopyAsync(folder, Guid.NewGuid() + "." + _storageFile.FileType);
    }
