在WPF窗口中嵌入EXE程序打开的窗口

在WPF中嵌入exe

软件已安装好，EXE所在路径为C:\Program Files\Company\Workstation\Software.exe
文中涉及到的具体名字已隐藏

第一次尝试

<Window x:Class="WpfApplication2.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:WpfApplication2"
        mc:Ignorable="d"
        Title="MainWindow" Width="500" Height="350" Loaded="Window_Loaded">
    <Grid>
    
    </Grid>
</Window>

public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }

        private void Window_Loaded(object sender, RoutedEventArgs e)
        {
            //启动
            var process = new Process();
            ProcessStartInfo info = new ProcessStartInfo("C:\\Program Files\\Company\\Workstation\\Software.exe");
            info.WindowStyle = ProcessWindowStyle.Minimized;
            Process.Start(info);
            var m_WindowName = "Software_name";
            IntPtr HWND = IntPtr.Zero;
            int times = 60 * 5;//给5分钟的启动时间
            while (times > 0)
            {
                times--;

                HWND = Class1.FindWindow(null, m_WindowName);
                if (HWND == IntPtr.Zero)  //稍等一会，不然可能找不到
                {
                    Thread.Sleep(1000);
                    continue;
                }

                break;
            }

            //当前窗口句柄
            IntPtr parent = new WindowInteropHelper(Application.Current.MainWindow).Handle;
            var hand = Class1.FindWindow(null, "MainWindow");

            //改变样式(去掉一圈)
            Class1.ShowWindow(HWND, Class1.SW_SHOW);
            Class1.EnableWindow(HWND, true);
            int style = Class1.GetWindowLong(HWND, Class1.GWL_STYLE);
            style = style & ~((int)Class1.WS_CAPTION) & ~((int)Class1.WS_THICKFRAME); 
            style |= ((int)Class1.WS_CHILD);
            Class1.SetWindowLong(HWND, Class1.GWL_STYLE, style);

            //放进去
            Class1.SetParent(HWND, parent);
        }
    }
}

效果如图

没有全部填充到WP的窗口中，只显示一部分，不是想要的效果，使用
Rect rect = new Rect();
Class1.GetWindowRect(parent, out rect);
显示的位置也不正确，找不到有效的解决办法，换了一种思路

第二次尝试

<Window x:Class="WpfApplication2.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:WpfApplication2"
        mc:Ignorable="d"
        Title="MainWindow" Width="500" Height="350" Loaded="Window_Loaded">
    <Grid>
        <Border x:Name="WndHost"></Border>
    </Grid>
</Window>

namespace WpfApplication2
{
    /// 

    /// MainWindow.xaml 的交互逻辑
    /// 
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }

        private void Window_Loaded(object sender, RoutedEventArgs e)
        {
            EmbeddedApp ea = new EmbeddedApp(WndHost, 100, 100);
            WndHost.Child = ea;
        }
    }
}

class EmbeddedApp : HwndHost, IKeyboardInputSink
    {
        private Border WndHoster;
        private double screenW, screenH;
        
        public EmbeddedApp(Border b, double sW, double sH)
        {
            WndHoster = b;
            screenW = sW;
            screenH = sH;
        }

        protected override HandleRef BuildWindowCore(HandleRef hwndParent)
        {
            //启动
            var process = new Process();
            ProcessStartInfo info = new ProcessStartInfo("C:\\Program Files\\Company\\Workstation\\Software.exe");
            info.WindowStyle = ProcessWindowStyle.Minimized;
            Process.Start(info);
            var m_WindowName = "Software_name";
            IntPtr HWND = IntPtr.Zero;
            int times = 60 * 5;//给5分钟的启动时间
            while (times > 0)
            {
                times--;

                HWND = Class1.FindWindow(null, m_WindowName);
                if (HWND == IntPtr.Zero)  //稍等一会，不然可能找不到
                {
                    Thread.Sleep(1000);
                    continue;
                }

                break;
            }

            //改变样式
            Class1.ShowWindow(HWND, Class1.SW_SHOW);
            Class1.EnableWindow(HWND, true);
            int style = Class1.GetWindowLong(HWND, Class1.GWL_STYLE);
            style = style & ~((int)Class1.WS_CAPTION) & ~((int)Class1.WS_THICKFRAME);
            style |= ((int)Class1.WS_CHILD);
            Class1.SetWindowLong(HWND, Class1.GWL_STYLE, style);

            //嵌入进去
            Class1.SetParent(HWND, hwndParent.Handle); ;
            return new HandleRef(this, HWND);
        }

        protected override void DestroyWindowCore(HandleRef hwnd)
        {
            Console.WriteLine("11");
        }
    }

结果exe打开的窗口可以完全嵌入到WPF打开的窗口中，完成想要的效果。
