問題描述

我的問題與在頁面之間傳遞數據有完全相同的問題，但僅適用于 Windows Phone 8.1(相對于 Windows Phone 7).問題來了:

I have the exact same question as Passing data from page to page, but only for Windows Phone 8.1 (opposed to Windows Phone 7). Here is the question:

我正在尋找有關如何在頁面之間傳遞數據的最佳實踐.

I'm looking for the best practice on how to pass data from page to page.

在頁面 A 中，我有一個觸發頁面 B 的按鈕.在頁面 B 我有 6 個文本框，允許用戶輸入信息.當用戶完成后，點擊一個按鈕將他們帶回頁面 A.

In Page A I have a button that fires off Page B. On Page B I have 6 textboxes that allow the user to enter information. When the user is done, the click on a button that brings them back to Page A.

我想將該數據傳遞回頁面 A.

I want to pass that data back to Page A.

我看到了以下建議:

在 WP8.1 運行時 - 對于 Silverlight，WP8.0 中使用的方法 應該仍然有效 - 您有兩個選擇:

In WP8.1 Runtime - for Silverlight, the methods used in WP8.0 still should work - you have couple of choces:

• 第一種可能也是最簡單的方法是使用 使用參數導航 - 如果它是可序列化類型，則不必將其轉換為 string:

• the first and probably the easiest way is to use Navigate with parameter - you don't have to convert it to string if it's a serializable type:

// let's assume that you have a simple class:
public class PassedData
{
   public string Name { get; set; }
   public int Value { get; set; }
}

// then you navigate like this:
Frame.Navigate(typeof(Page1), new PassedData { Name = "my name", Value = 10 });

// and in target Page you retrive the information:
protected override void OnNavigatedTo(NavigationEventArgs e)
{
    PassedData data = e.Parameter as PassedData;
}
