为 Windows Phone 8.1 在页面之间传递数据

问题描述

我的问题与在页面之间传递数据有完全相同的问题，但仅适用于 Windows Phone 8.1(相对于 Windows Phone 7).问题来了:

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:

我正在寻找有关如何在页面之间传递数据的最佳实践.

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

在页面 A 中，我有一个触发页面 B 的按钮.在页面 B 我有 6 个文本框，允许用户输入信息.当用户完成后，点击一个按钮将他们带回页面 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.

我想将该数据传递回页面 A.

I want to pass that data back to Page A.

我看到了以下建议:

推荐答案

在 WP8.1 运行时 - 对于 Silverlight，WP8.0 中使用的方法 应该仍然有效 - 您有两个选择:

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

• 第一种可能也是最简单的方法是使用 使用参数导航 - 如果它是可序列化类型，则不必将其转换为 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;
}
