在Windows10通用应用程序c#中保存FolderPicker位置以备下次使用

using Windows.Storage;
using Windows.Storage.Pickers;

// 保存FolderPicker位置
private async void SaveFolderPickerLocation()
{
    // 创建FolderPicker实例
    FolderPicker folderPicker = new FolderPicker();
    folderPicker.SuggestedStartLocation = PickerLocationId.ComputerFolder;

    // 显示FolderPicker并等待用户选择文件夹
    StorageFolder folder = await folderPicker.PickSingleFolderAsync();

    if (folder != null)
    {
        // 获取选择的文件夹路径
        string folderPath = folder.Path;

        // 保存文件夹路径到本地存储
        ApplicationData.Current.LocalSettings.Values["FolderPickerLocation"] = folderPath;
    }
}

// 加载上次保存的FolderPicker位置
private void LoadFolderPickerLocation()
{
    // 从本地存储中获取上次保存的文件夹路径
    if (ApplicationData.Current.LocalSettings.Values.ContainsKey("FolderPickerLocation"))
    {
        string folderPath = ApplicationData.Current.LocalSettings.Values["FolderPickerLocation"].ToString();

        // 使用文件夹路径进行相应的操作
        // ...
    }
}
