InvalidOperationException 由 InitializeComponent

Question

如果我从 MainWindow Class 打开一个新的 Window，我得到一个 InvalidOperationException。通过调用 InitializeComponent()-Method 抛出异常。

我不知道该怎么办。

ItemWindow itemWindow = new ItemWindow()
{
   WindowStartupLocation = WindowStartupLocation.CenterScreen,
   Topmost = true
};
itemWindow.ShowDialog();

第二次调用方法出现错误

消息：

The Application object is being shut down.

Source: PresentationFramework

The StackTrace:

at System.Windows.Application.GetResourcePackage(Uri packageUri)
at System.Windows.Application.LoadComponent(Object component, Uri resourceLocator)
at Project.View.ItemWindow.InitializeComponent() in d:\Documents\Visual Studio 2012\Projects\Project\View\ItemWindow.xaml:line 1.
at Project.View.ItemWindow..ctor() in d:\Documents\Visual Studio 2012\Projects\ Project \View\ItemWindow.xaml.cs:line 45.
at Project.View.EditButton_OnClick(Object sender, RoutedEventArgs e) in d:\Documents\Visual Studio 2012\Projects\ Project \View\MainWindow.xaml.cs:line 479.

编辑: 问题只出现在调试模式下。

Edit2: 这个问题不仅出现在debug模式，releas模式也有。

找到原因了。

主应用程序以 windows 形式编写。在选项卡中，应用程序使用 WPF-UserControl 执行 elementhost。此 UserControl 打开 WPF-Window。通过关闭此 WPF-Window，WPF-UserControl 也将关闭。（严重关机）

Answer 1

此消息表示您的应用程序开始关闭。关机可以通过以下方式启动：

如果 Application.ShutdownMode 等于 OnLastWindowClose，则关闭所有 windows。
如果 Application.ShutdownMode 等于 OnMainWindowClose，则关闭主 window。
正在手动调用关机。

所以检查这种情况，因为它们会导致问题。

编辑： 因为您有第一个列出的原因，所以您应该将 Application.ShutdownMode 更改为 OnExplicitShutdown。
