Csharp 应用程序启动器，可 Select 物理屏幕

我无法根据我的屏幕布局获得按钮布局(使用按钮进行模拟).

我希望能够获得与屏幕上现有按钮类似的相同分布的按钮.

相反，我得到了这样的结论:

我目前的脚本是这样的(这是我实现的最接近最终布局的脚本):

using System.Runtime.InteropServices;

namespace WebStack_Deployer_for_Docker.Forms
{
    public partial class DisplaySelector : Form
    {
        private const int SW_SHOWNORMAL = 1;

        [StructLayout(LayoutKind.Sequential)]
        private struct POINT
        {
            public int X;
            public int Y;
        }

        [StructLayout(LayoutKind.Sequential)]
        private struct RECT
        {
            public int Left;
            public int Top;
            public int Right;
            public int Bottom;
        }

        [StructLayout(LayoutKind.Sequential)]
        private struct WINDOWPLACEMENT
        {
            public int length;
            public int flags;
            public int showCmd;
            public POINT ptMinPosition;
            public POINT ptMaxPosition;
            public RECT rcNormalPosition;
        }

        public readonly int screens = Screen.AllScreens.Length;

        private Panel panelMonitors;

        private const int ButtonWidth = 160;

        private const int ButtonHeight = 100;

        public DisplaySelector()
        {
            InitializeComponent();
            InitializeMonitorSelection();
        }

        private void InitializeMonitorSelection()
        {
            panelMonitors = new Panel
            {
                Dock = DockStyle.Fill
            };
            Controls.Add(panelMonitors);

            Screen[] allScreens = Screen.AllScreens;
            Array.Sort(allScreens, (a, b) => a.Bounds.X.CompareTo(b.Bounds.X));

            int totalScreens = allScreens.Length;

            int startX = (ClientSize.Width - totalScreens * (ButtonWidth + 20)) / 2;
            int startY = (ClientSize.Height - ButtonHeight) / 2;

            for (int i = 0; i < totalScreens; i++)
            {
                int monitorIndex = i;
                Button monitorButton = new Button
                {
                    Text = $"Pantalla #{monitorIndex + 1}",
                    Tag = monitorIndex,
                    Size = new Size(ButtonWidth, ButtonHeight),
                    // Calcula la posición X y Y del botón de acuerdo a la disposición real de las pantallas
                    Location = CalculateButtonPosition(startX, startY, monitorIndex, totalScreens, ButtonWidth)
                };

                monitorButton.Click += MonitorButton_Click;
                panelMonitors.Controls.Add(monitorButton);
            }
        }

        private Point CalculateButtonPosition(int startX, int startY, int monitorIndex, int totalScreens, int buttonWidth)
        {

            int positionX = startX;
            if (monitorIndex > 0)
            {
                positionX += (buttonWidth + 20) * monitorIndex;
            }

            int positionY = startY;

            if (totalScreens > 1)
            {
                if (monitorIndex == 0)
                {
                    positionY -= ButtonHeight / 2 + 20;
                }
                else if (monitorIndex == totalScreens - 1)
                {
                    positionY += ButtonHeight / 2 + 20;
                }
            }

            return new Point(positionX, positionY);
        }

        private void MonitorButton_Click(object sender, EventArgs e)
        {
            Button clickedButton = (Button)sender;
            int monitorIndex = (int)clickedButton.Tag;
            MessageBox.Show($"Has seleccionado el Monitor #{monitorIndex}");
            MoveToDisplay(monitorIndex);
        }

        public static void MoveToDisplay(int display)
        {
            if (Screen.AllScreens.Length > 1)
            {
                IntPtr windowHandle = GetForegroundWindow();

                WINDOWPLACEMENT placement = new WINDOWPLACEMENT
                {
                    length = Marshal.SizeOf(typeof(WINDOWPLACEMENT))
                };
                GetWindowPlacement(windowHandle, ref placement);

                Rectangle secondMonitor = Screen.AllScreens[display].WorkingArea;
                int windowWidth = placement.rcNormalPosition.Right - placement.rcNormalPosition.Left;
                int windowHeight = placement.rcNormalPosition.Bottom - placement.rcNormalPosition.Top;

• 按钮的顺序.
• 与系统中建立的配置类似的按钮布局.
