C# Process.HasExited为true，但进程仍处于活动状态

在等待某个进程退出时，我观察到，虽然该进程仍存在于任务管理器中，但process.HasExited为true，process.WaitForExit（0）返回false。知道为什么吗

这个问题与其他问题不同，因为在这个问题上，WaitForExit返回了true

{编辑2}

可以看出，退出进程正在全局析构函数上引发异常，可能导致调试对话框打开。（由于种种原因，在我的环境中看不到它）所以这个过程是半死不活的？退出但未返回

{编辑}

在进程上调用CloseMainWindow（），然后我等待它退出。主窗口确实关闭了。但这一过程仍然没有结束

从调试器添加对象的转储 请注意，signaled为false，haveExitTime为false，ExitCode返回异常。刚刚退出是真的

有何不同？这里没有任何东西表明这一点，或者我们可以使用它。你确定这不是同一个EXE的不同实例吗？SLak-是的，只有一个正在运行的实例，并且进程id匹配。该进程可能产生了另一个进程并继续运行，然后返回。但是WaitForExit也将是真的，不是吗？
