在页面之间共享数据的最佳实践 [英] Best practice for sharing data between pages

问题描述

我想知道在UWP的页面之间发送变量(例如"selectedItem"等)的最佳实践是什么?仅创建每个Page都知道的静态全局变量类是一个好主意吗?

I was wondering what the best practice is for sending variables like 'selectedItem' and so on between pages in UWP? Is it a good idea to just create a static global variable class that every Page knows of?

推荐答案

我将在这里总结Microsoft 最佳实践 :

I'm going to sum up Microsofts Best Practice here:

用于简单数据(例如字符串):
使用 Frame.Navigate(TypeName, Object) 方法，其中第二种方法参数应始终为字符串(即使它允许对象).然后可以从NavigationEventArgs.Parameter . aspx"rel =" noreferrer> Frame.Navigated 事件处理程序.

For simple data (like strings):
Use the Frame.Navigate(TypeName, Object) method, where as the second argument should always be a string (even if it allows objects). The second argument can then be extracted from the NavigationEventArgs.Parameter in the Frame.Navigated event handler.

用于复杂数据(字符串除外):
您可以根据应用程序的大小和复杂程度在这里选择两个选项:

For complex data (anything besides strings):
You may choose from two options here, depending on the size and complexity of your app:

• 直接管理对App类中任何复杂数据的引用
• 或在属于App类成员的任何 Manager 类中保留对它们的引用. (例如NavigationDataManager).

• Either manage a reference to any complex data inside your App class directly
• Or keep a reference to them in any kind of Manager class, that is a member of your App class. (e.g. NavigationDataManager).
