Windows 应用商店应用:我的应用在切换后终止 [英] Windows Store Apps: my app terminates after being switched

问题描述

我正在构建一个 Windows 8 应用.

I'm building a Windows 8 app.

我的问题是当用户切换到另一个应用程序或开始时，应用程序终止.在侧边栏中，我发现应用的预览显示启动画面，当我点击应用时，它从头开始.

My problem is when the user switches to another app or goes to start, the app terminates. In the side bar I find the preview of the app to be displaying the splash screen, when I click on the app it starts from the beginning.

这里有什么问题，可能是内存问题吗?在任务管理器中，我的应用占用了 40 MB 的内存，是否太多了?

What can be the problem here, could it be a memory issue ? In the task manager my app takes 40 MB of memory, is that too much ?

事件查看器在应用崩溃时显示以下内容:

The Event Viewer shows the following when the app crashes:

推荐答案

从您的堆栈跟踪来看，暂停管理器似乎正在抛出异常.我在暂停管理器中发现的异常的最常见原因是尝试在页面之间传递复杂对象作为导航参数.如果您要传递完整的业务对象，请尝试只传递 ID.我知道这很疯狂，但这就是默认实现的方式.

From your stack trace it looks like the suspension manager is throwing an exception. The most common cause of exceptions I've found in the suspension manager is in trying to pass complex objects between pages as a navigation parameter. If you are passing a complete business object around, then try just passing the ID. I know it's crazy, but that's the way it is with the default implementation.
