查找 WPF 窗口的句柄
Windows 窗体有一个属性 win1.Handle，如果我记得的话，它返回主窗口句柄的句柄？
有没有等效的方法来获取 WPF 窗口的句柄？
我在网上找到了以下代码，
IntPtr windowHandle =
new WindowInteropHelper(Application.Current.MainWindow).Handle;
但我认为这对我没有帮助，因为我的应用程序有多个窗口。
Windows forms had a property win1.Handle which, if I recall, returns the handle of the main window handle?
Is there an equivalent way to get the handle of a WPF Window?
I found the following code online,
IntPtr windowHandle =
new WindowInteropHelper(Application.Current.MainWindow).Handle;
But I don't think that will help me because my application has multiple windows.

那么，不用传递
Application.Current.MainWindow，只需传递对您想要的窗口的引用：new WindowInteropHelper(this).Handle等等。Well, instead of passing
Application.Current.MainWindow, just pass a reference to whichever window it is you want:new WindowInteropHelper(this).Handleand so on.只需将您的窗口与 WindowsInteropHelper 类一起使用：
现在，您正在请求应用程序的主窗口，其中总会有一个。但是，您可以在任何 Window 上使用相同的技术，只要它是 System.Windows.Window 派生的 Window 类。
Just use your window with the WindowsInteropHelper class:
Right now, you're asking for the Application's main window, of which there will always be one. You can use this same technique on any Window, however, provided it is a System.Windows.Window derived Window class.
你可以使用：
you can use :
在我的用例中，我需要在启动期间主窗口的句柄，无论我做什么，我都无法让
new WindowInteropHelper(...).Handle返回除空句柄之外的任何内容因为窗口尚未初始化。您可以使用 < code>EnsureHandle() 方法，如果句柄尚不存在，它将创建句柄，如果存在，则返回当前句柄。
应用程序启动后，它会继续使用相同的句柄，不会出现问题。
In my use case I needed a handle to the main window during startup, and no matter what I did I couldn't get
new WindowInteropHelper(...).Handleto return anything other than a null handle since the window hadn't been initialized yet.You can use the
EnsureHandle()method instead, which will create the handle if it doesn't already exist, or return the current one if it does exist.Once the application has started, it continues using the same handle without issue.
如果您出于某种原因想要应用程序的所有
Window的窗口句柄，则可以使用Application.Windows属性获取所有 Windows，然后使用WindowInteropHandler来获取它们的句柄，正如您已经演示的那样。If you want window handles for ALL of your application's
Windows for some reason, you can use theApplication.Windowsproperty to get at all the Windows and then useWindowInteropHandlerto get at their handles as you have already demonstrated.在我的例子中，在 OnLoaded() 事件之后工作。在构造函数中它给出了一个零句柄。
Works after OnLoaded() event in my case. In the constructor it gives a zero handle.
