如何获得Window实例的hWnd？ [英] How to get the hWnd of Window instance?

问题描述

我的WPF应用程序有多个窗口，我需要能够得到每个Window实例的hWnd，这样我可以在Win32 API调用中使用它们。

My WPF application has more than one window, I need to be able to get the hWnd of each Window instance so that I can use them in Win32 API calls.

我想做些什么例子：

Window myCurrentWindow = Window.GetWindow(this);
IntPtr myhWnd = myCurrentWindow.hWnd; // Except this property doesn't exist.

什么是做到这一点的最好方法是什么？

What's the best way to do this?

推荐答案

WindowInteropHelper 是你的朋友。它有一个接受窗口参数的构造函数，和处理返回其窗口句柄属性。

WindowInteropHelper is your friend. It has a constructor that accepts a Window parameter, and a Handle property that returns its window handle.

Window window = Window.GetWindow(this);
var wih = new WindowInteropHelper(window);
IntPtr hWnd = wih.Handle;
