一
true
HasExited
个值,指示关联进程已正常终止或异常。 可以通过调用
CloseMainWindow
Kill
或强制关联进程退出。 如果句柄对进程打开,则操作系统会在进程退出时释放进程内存,但保留有关进程的管理信息,例如句柄、退出代码和退出时间。 若要获取此信息,可以使用
ExitCode
和
ExitTime
属性。 这些属性会自动填充此组件启动的进程。 当与系统进程关联的所有
Process
组件被销毁并不再保留退出进程的句柄时,将释放管理信息。
进程可以独立于代码终止。 如果使用此组件启动进程,系统会自动更新值
HasExited
,即使关联的进程独立退出也是如此。
当标准输出被重定向到异步事件处理程序时,当此属性返回
true
时,输出处理可能尚未完成。 若要确保异步事件处理已完成,请在检查
HasExited
之前调用
WaitForExit()
不带参数的重载。
