我正在尝试,但到目前为止我发现的一切似乎都以 GUI 和表单应用程序为中心。那不是我正在使用的。
最终它将成为一项服务,但在完成之前我将它作为一个普通应用程序运行,问题是如果我只是不小心关闭它,它会使另一个服务挂起长达 30 分钟,并出现错误数据. 我虽然很容易添加一个监听器来捕捉正在关闭的应用程序。
但我就是想不通。

在这里,您有一个完美的解决方案来满足您的需求:
该代码检测将关闭应用程序的所有可能事件:
namespace Detect_Console_Application_Exit2
{
class Program
{
private static bool isclosing = false;
static void Main(string[] args)
{
SetConsoleCtrlHandler(new HandlerRoutine(ConsoleCtrlCheck), true);
Console.WriteLine("CTRL+C,CTRL+BREAK or suppress the application to exit");
while (!isclosing) ;
}
private static bool ConsoleCtrlCheck(CtrlTypes ctrlType)
{
// Put your own handler here
switch (ctrlType)
{
case CtrlTypes.CTRL_C_EVENT:
isclosing = true;
Console.WriteLine("CTRL+C received!");
break;
case CtrlTypes.CTRL_BREAK_EVENT:
isclosing = true;
Console.WriteLine("CTRL+BREAK received!");
break;
case CtrlTypes.CTRL_CLOSE_EVENT:
isclosing = true;
Console.WriteLine("Program being closed!");
break;
case CtrlTypes.CTRL_LOGOFF_EVENT:
case CtrlTypes.CTRL_SHUTDOWN_EVENT:
isclosing = true;
Console.WriteLine("User is logging off!");
break;
}
return true;
}
#region unmanaged
// Declare the SetConsoleCtrlHandler function
// as external and receiving a delegate.
[DllImport("Kernel32")]
public static extern bool SetConsoleCtrlHandler(HandlerRoutine Handler, bool Add);
// A delegate type to be used as the handler routine
// for SetConsoleCtrlHandler.
public delegate bool HandlerRoutine(CtrlTypes CtrlType);
// An enumerated type for the control messages
// sent to the handler routine.
public enum CtrlTypes
{
CTRL_C_EVENT = 0,
CTRL_BREAK_EVENT,
CTRL_CLOSE_EVENT,
CTRL_LOGOFF_EVENT = 5,
CTRL_SHUTDOWN_EVENT
}
#endregion
}
}

如果要在应用程序内部处理事件,
如果是windows服务,
如果是 WCF 服务 ,可以使用ServiceHost.Closed事件。ServiceHost 从 Communication Host 继承 Closed(和相关事件)
如果要在单独的应用程序中处理事件,可以使用Process.Exited事件。
var serviceProcesses = Process.GetProcessesByName("service.exe");
if(serviceProcesses != null && serviceProcesses.Length>0)
{
serviceProcesses[0].Exited += OnServiceClosed;
}
AppDomain.CurrentDomain.ProcessExit
事件?
