在Xaml頁面之間進行數據共享

Question

我正在開發我的第一個Windows Phone應用程序及其天氣應用程序。我在主頁面中會顯示一個列表，顯示國家名稱和當前溫度。現在，當我點擊任何一個國家在列表中，頁面被導航到Xaml頁面，該頁面將顯示關於天氣狀況的詳細信息。

但是我面臨的問題是當我從那裏導航到另一個Xaml頁面時，它應該給我列表中下一個國家的詳細內容與前面相同的格式。

我可以知道這是怎麼可能的，因爲我在這個領域很新穎。

在此先感謝

我想此XAML頁面，根據該列表被改變和滑動控制。一定幫助我。

感謝

基本上你可以移動到新頁面時，在這裏早些時候How to pass values (parameters) between XAML pages?問題說明與URL傳遞數據。

或者您可以將數據存儲在單例中，並更新&從不同的地方讀取它，如Passing data from page to page問題所示。
