Question

我有一个使用 c++ 编写的 exe 程序，
我想在 exe 打开、关闭或最小化
时执行一些操作我想知道使用 c#.net 是否可以实现这种功能？

可以发送windows消息。您还可以使用管道名称在窗口上进行控制

A simple message pump looks like this:
[Serializable, StructLayout(LayoutKind.Sequential)]
public struct MSG
{
    public IntPtr hwnd;
    public int message;
    public IntPtr wParam;
    public IntPtr lParam;
    public int time;
    public int pt_x;
    public int pt_y;
}

[DllImport("user32.dll", CharSet = CharSet.Ansi)]
public static extern bool GetMessage([In, Out] ref MSG msg, IntPtr hWnd, int MsgFilterMin,  int uMsgFilterMax);

[DllImport("user32.dll", CharSet = CharSet.Auto)]
public static extern IntPtr DispatchMessage([In] ref MSG msg);


[DllImport("user32.dll", CharSet = CharSet.Unicode, SetLastError = true)]
public static extern uint RegisterWindowMessage(string lpString);

[DllImport("user32.dll", SetLastError = true)]
public static extern IntPtr SendMessage(IntPtr hWnd, uint Msg, IntPtr wParam, IntPtr lParam);


    // #1
    MSG msg = new MSG();
    while (GetMessage(ref msg, IntPtr.Zero, 0, 0))
    {
        DispatchMessage(ref msg);
    }

    // #2
    uint UWM_UART_CTRL_TRS = Win32Api.RegisterWindowMessage("BT_UARTCTRL_TRANSFER");
    Win32Api.SendMessage(HWND_BROADCAST, UWM_UART_CTRL_TRS, (IntPtr)0, (IntPtr)0);

    // #3
    uint UWM_UART_CTRL_TRS = Win32Api.RegisterWindowMessage("BT_UARTCTRL_TRANSFER");
    Win32Api.SendMessage(HWND_BROADCAST, UWM_UART_CTRL_TRS, (IntPtr)1, (IntPtr)0);
