SuspensionManager当应用程序已超过1页在Windows 8 XAML / C＃应用程序错误 [英] SuspensionManager Error when application has more than 1 page in windows 8 XAML/C# app

问题描述

我正在写一个Windows 8的XAML / C＃应用程序，并与会话管理器有点问题。

I'm writing a windows 8 XAML/C# app and have a little problem with the session manager.

在我App.xaml.cs我OnSuspending方法如下像这样的：

Within my App.xaml.cs my OnSuspending method looks like this:

    private async void OnSuspending(object sender, SuspendingEventArgs e)
    {
        var deferral = e.SuspendingOperation.GetDeferral();
        //TODO: Save application state and stop any background activity
        await SuspensionManager.SaveAsync();
        deferral.Complete();
    }

我已经临时用户我rootFrame与在App.xaml中的OnLaunched方法SuspensionManager的.cs：

I have registed my rootFrame with the SuspensionManager in the OnLaunched method in App.xaml.cs:

SuspensionManager.RegisterFrame(rootFrame, "AppFrame");

所以，在我的应用程序的第一页，我已经重写了即时存档方法。它看起来是这样的：

So, in the first page of my app I have overriden the SaveState method. It looks like this:

    protected override void SaveState(Dictionary<string, object> pageState)
    {
        Save(true);

        base.SaveState(pageState);
    }

当应用程序被停用了此方法被调用，这一切工作正常。

When the application is suspended this method is called and it all works fine.

我与即时存档方法的第2页相同的第一个（如上述如此）。

I have a 2nd page with the SaveState method the same as the first (so as above).

当我导航到第2页从我的第一页，并暂停该应用程序，无论是即时存档方法被调用，应用程序崩溃，出现以下错误：

When I navigate to the 2nd page from my 1st page and suspend the application neither of the SaveState methods are called and the application crashes with the following error:

SuspensionManager失败：未指定的错误

SuspensionManager failed: Unspecified error

辉煌！没有太多的信息有!!

Brilliant!! Not much information there!!

所以，我需要做任何多页的SuspensionManager不同？

So, do I need to do anything different with the SuspensionManager with multiple pages?

在此先感谢

推荐答案

SuspensionManager Manager与多页 - 没有问题。鉴于小的背景下，我建议如下：

SuspensionManager manager works with multiple pages - no issues. given the little context, i would suggest following:

1. 请问您创造一个VS项目时是自动生成的共同文件进行任何更改
   使用网格的应用程序模板？如果是的话 - 尝试建立一个新的项目


2. 您是否传递是在frame.navigate调用非序列化的参数？这是不可能的，因为在这种情况下 - 你可以在输出窗口像这样看 - WinRT的信息：GetNavigationState不支持被传递给Frame.Navigate参数类型的序列化
