public class WindowsClose : MonoBehaviour
{
    // 声明需要使用的Windows API函数
    [DllImport("user32.dll", SetLastError = true)]
    [return: MarshalAs(UnmanagedType.Bool)]
    static extern bool CloseWindow(IntPtr hWnd);

    //[DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
    //static extern IntPtr FindWindow(string lpClassName, string lpWindowName);

    // 调用CloseWindow函数关闭窗口 不触发 ondestory onapplicationquit
    public void CloseAppWindow()
    {
        // 获取当前窗口句柄
        IntPtr windowHandle = FindWindow(null, "WS Display Settings");

        // 关闭窗口
        if (windowHandle != IntPtr.Zero)
        {
            CloseWindow(windowHandle);
        }

    }




    [DllImport("user32.dll", EntryPoint = "FindWindow")]

    [DllImport("user32.dll", EntryPoint = "PostMessage", SetLastError = true)]
    public static extern bool PostMessage(IntPtr hwnd, uint Msg, uint wParam, uint lParam);

    public const int WM_SYSCOMMAND = 0x0112;
    public const int SC_CLOSE = 0xF060;
    /// <summary>
    /// 调用 PostMessage 函数关闭窗口  可触发 ondestory onapplicationquit

        IntPtr hwnd1 = FindWindow(null, "WS Display Settings");
        PostMessage(hwnd1, WM_SYSCOMMAND, SC_CLOSE, 0);
