如何在代码中查找WPF控件的父窗口或WinForm?

我想明白了!

var presentationSource = (HwndSource)PresentationSource.FromVisual(child);
var parentHandle = presentationSource.Handle;

[DllImport("user32.dll")]
        public static extern int GetParent(int hwnd);

        public int GetParentWindowHandle(Visual child)
        {
            HwndSource presentationSource = (HwndSource)PresentationSource.FromVisual(child);

            int parentHandle = presentationSource.Handle.ToInt32();
            int handle = parentHandle;

            while (parentHandle != 0)
            {
                handle = parentHandle;
                parentHandle = ApplicationHelperInterop.GetParent(parentHandle);
            }

            return handle;
        }

然后你可以循环通过 System.Windows.Forms.Application.OpenForms 集合以查找与上面GetParentWindowHandle方法的返回值相对应的WinForm。
