Microsoft UIAutomation无法移动Edge浏览器窗口

如何解决Microsoft UIAutomation无法移动Edge浏览器窗口

我结合了来自两个不同来源的经验，以使用UIAutomation检测打开的窗口并移动窗口：

1. Detect the opening of a new window in C#
2. Move a UI Automation Element

几乎每个应用程序窗口（Win32应用程序和UWP应用程序）都可以移动。除了Microsoft Edge浏览器窗口！

问题：有谁知道如何使用UIAutomation移动Edge窗口？有谁知道Edge浏览器有什么特别之处，可以阻止它遵循Microsoft自己的UIAutomation库？

这是我完整的控制台应用程序代码（必需：添加对UIAutomationClient和UIAutomationTypes的引用）：

using System;
using System.Threading;
using System.Windows.Automation;

namespace UiAutomationTest
{
    class Program
    {
        static void Main(string[] args)
        {
            Automation.AddAutomationEventHandler(eventId: WindowPattern.WindowOpenedEvent,element: AutomationElement.RootElement,scope: TreeScope.Children,eventHandler: OnWindowOpened);
            Console.ReadLine();
            Automation.RemoveAllEventHandlers();
        }

        private static void OnWindowOpened(object sender,AutomationEventArgs e)
        {
            try
            {
                var element = sender as AutomationElement;
                if (element != null)
                {
                    var hWnd = new IntPtr(element.Current.NativeWindowHandle);
                    Console.WriteLine($"Opened: {element.Current.Name} (Pid:{element.Current.ProcessId}),hWnd:{Convert.ToInt32(hWnd.ToString())}");
                    var _windowPattern = GetControlPattern(element,WindowPattern.Pattern) as WindowPattern;
                    if (_windowPattern == null)
                    {
                        Console.WriteLine("WindowPattern is null! Aborting.");
                        return;
                    }

                    if (false == _windowPattern.WaitForInputIdle(10000))
                    {
                        Feedback("Object not responding in a timely manner.");
                        return;
                    }
                    Console.WriteLine("Window is ready for input");

                    var _transformPattern = GetControlPattern(element,TransformPattern.Pattern) as TransformPattern;

                    if (_transformPattern == null)
                    {
                        Console.WriteLine("TransformPattern is null! Aborting.");
                        return;
                    }

                    // Is the TransformPattern object moveable?
                    if (_transformPattern.Current.CanMove)
                    {
                        Console.WriteLine("Waiting 3 seconds before move...");

                        // Wait a bit
                        Thread.Sleep(3000);

                        // Move element
                        _transformPattern.Move(250,500);
                        Console.WriteLine("Window was moved!");
                    }
                    else
                    {
                        Feedback("Window is not moveable.");
                    }
                }
            }
            catch (Exception ex)
            {
                Console.WriteLine($"{ex.GetType()}: {ex.Message}\n{ex.StackTrace}");
            }
        }

        /// <summary>
        /// Gets a specified control pattern.
        /// </summary>
        /// <param name="ae">The automation element we want to obtain the control pattern from.</param>
        /// <param name="ap">The control pattern of interest.</param>
        /// <returns>A ControlPattern object.</returns>
        private static object GetControlPattern(AutomationElement ae,AutomationPattern ap)
        {
            if (false == ae.TryGetCurrentPattern(ap,out object oPattern))
            {
                Feedback("Object does not support the " + ap.ProgrammaticName + " Pattern");
                return null;
            }

            Feedback("Object supports the " + ap.ProgrammaticName + " Pattern.");
            return oPattern;
        }

        private static void Feedback(string message)
        {
            Console.WriteLine(message);
        }
    }
}

这是一个视频，显示我可以打开Internet Explorer并移动它，Chrome并移动它，但是Edge不会移动！

最后，我什至尝试使用老式的Win32 API，例如EnumWindows，MoveWindow，SetWindowPlacement和SetWindowPos。 Edge浏览器似乎位于ApplicationFrameHost.exe进程窗口的内部。当我尝试移动窗口时，得到的结果与使用UIAutomation库的结果相同：它“说”通过了，但是窗口实际上并没有移动！
