C# winforms程序中的XAML窗口

当我在Winforms窗体上使用一个按钮打开一个用XAML创建的窗口时，它第一次正常工作，然后我关闭该窗口并重新单击该按钮，但是在正在创建的窗口的

InitializeComponent（）

上，我得到一个异常消息，

“应用程序对象正在关闭”

我曾尝试将其作为用户控件托管在

元素主机中，但问题仍然相同。
在普通应用程序中，WinForms和WPF环境都由
应用程序
类型启动，该类型通常从
主
方法调用

在这里，WPF环境不会发生这种情况，这会导致问题。如果要从WinForms应用程序显示WPF窗口，则需要启动dispatcher。最好在新线程中执行此操作，以便可以根据需要关闭任意次数：

private void ShowWpfWindow()
{
    // This delegate is executed in new thread
    ThreadStart showWindow = () =>
    {
        var window = new RestoreSettingsWindow(); // your window to show

        // making sure that the thread can exit when the window is closed
        window.Closed += (sender, e) => Dispatcher.InvokeShutdown();

        window.Show();

        // Starts the dispatcher in the new thread and does not let the thread exit.
        // This call is returned when the window is closed (due to the Closed event handler)
        System.Windows.Threading.Dispatcher.Run();
    };

    // Creating and starting an STA thread for the WPF window
    Thread wpfThread = new Thread(showWindow);
    wpfThread.SetApartmentState(ApartmentState.STA);
    wpfThread.Priority = ThreadPriority.Normal;
    wpfThread.Start();
}

private void ShowWpfWindow()
{
    // This delegate is executed in new thread
    ThreadStart showWindow = () =>
    {
        var window = new RestoreSettingsWindow(); // your window to show

        // making sure that the thread can exit when the window is closed
        window.Closed += (sender, e) => Dispatcher.InvokeShutdown();

        window.Show();

        // Starts the dispatcher in the new thread and does not let the thread exit.
        // This call is returned when the window is closed (due to the Closed event handler)
        System.Windows.Threading.Dispatcher.Run();
    };

    // Creating and starting an STA thread for the WPF window
    Thread wpfThread = new Thread(showWindow);
    wpfThread.SetApartmentState(ApartmentState.STA);
    wpfThread.Priority = ThreadPriority.Normal;
    wpfThread.Start();
}
