在Windows Phone 8.1 C＃中保存数据

Question

我想在关闭应用程序并重新打开应用程序时将数据保存在应用程序中...

private void Button_Click(object sender, RoutedEventArgs e)
    {


        textblock.Visibility = Visibility.Visible;

    }

我要添加此代码以保存数据以关闭应用程序吗？！

是Windows Phone 8.1 RT吗？ 如果是，那么您可以这样做：

 var localSettings = Windows.Storage.ApplicationData.Current.LocalSettings;
 if (localSettings.Values.ContainsKey("textblockVisibility"))
 {
     var value = localSettings.Values["textblockVisibility"];
     textblock.Visibility = (bool) value ? Visibility.Visible : Visibility.Collapsed;
 }
 else
 {
      var valueToSave = textBlock.Visibility == Visibility.Visible ? true : false;
      localSettings.Values.Add("textblockVisibility", valueToSave);
 }
