我有一个控制台应用程序的主线程,它以这种方式运行很少的外部进程
private static MyExternalProcess p1;
private static MyExternalProcess p2;
private static MyExternalProcess p3;
public void Main() {
p1 = new MyExternalProcess();
p2 = new MyExternalProcess();
p3 = new MyExternalProcess();
p1.startProcess();
p2.startProcess();
p3.startProcess();
}
public static void killEveryoneOnExit() {
p1.kill();
p2.kill();
p3.kill();
}
class MyExternalProcess {
private Process p;
...
public void startProces() {
// do some stuff
PlayerProcess = new Process();
....
PlayerProcess.Start();
// do some stuff
}
public void kill() {
// do some stuff
p.Kill();
}
}
我需要做的是:当主线程被中断时(退出按钮或ctrl + c),其他进程应被终止。 如何在CTRL + C或Exit(X)按钮上触发我的方法killEveryoneOnExit?

根据您的问题,您需要捕捉两个事件。
如果你把这两个放在你的例子中,你会得到这样的东西:
static ConsoleEventDelegate handler;
private delegate bool ConsoleEventDelegate(int eventType);
[DllImport("kernel32.dll", SetLastError = true)]
private static extern bool SetConsoleCtrlHandler(ConsoleEventDelegate callback, bool add);
private static MyExternalProcess p1;
public static void Main()
{
Console.CancelKeyPress += delegate
{
killEveryoneOnExit();
};
handler = new ConsoleEventDelegate(ConsoleEventCallback);
SetConsoleCtrlHandler(handler, true);
p1 = new MyExternalProcess();
p1.startProcess();
}
public static void killEveryoneOnExit()
{
p1.kill();
}
static bool ConsoleEventCallback(int eventType)
{
if (eventType == 2)
{
killEveryoneOnExit();
}
return false;
}
