在Windows Phone 8.1 C＃中保存數據

Question

我想在關閉應用程序並重新打開應用程序時將數據保存在應用程序中...

private void Button_Click(object sender, RoutedEventArgs e)
    {


        textblock.Visibility = Visibility.Visible;

    }

我要添加此代碼以保存數據以關閉應用程序嗎？！

是Windows Phone 8.1 RT嗎？ 如果是，那么您可以這樣做：

 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);
 }
