I wonder whether this kind of functionality is possible using c#.net

you can send windows message. 您可以发送Windows消息。 you also control on the window by using pipe name
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);
Native .NET Process
class has a functionality for an event fired when a process is closed . 本机.NET
Process
类具有关闭进程时触发的事件的功能。
Also process monitoring in C# is partially discussed in this post . 在这篇文章中还将部分讨论C#中的过程监视。
Considering this, you'll have to use Windows Management Instrumentation to track wide range of specific process events. 考虑到这一点,您必须使用Windows Management Instrumentation来跟踪各种特定的过程事件。
