关于excel：如何从C＃控制台停止办公应用程序

How to stop office application from C# console

本问题已经有最佳答案，请猛点这里访问。

给定以下代码(控制台应用程序C)，Word应用程序将在大约300-400毫秒后停止，但Excel应用程序将继续运行。我找不到一种方法来阻止它(不扼杀进程)。

有什么建议吗？

所以有几件事向我扑来。

您不会在Excel应用程序本身上调用Quit。这是它关闭的信号。

您还需要确保在工作簿上调用Close。

确保关闭后，将所有对象设置为空。

我还发现，在我使用过的所有对象上，不仅调用Marshal.ReleaseComObject，而且调用Marshal.FinalReleaseComObject也是很有帮助的。

你是双点，这意味着你泄露了一堆参考资料。不好的做法，会鼓励Excel四处闲逛

最后，为了真正确保我杀死Excel，在我完成以上所有操作之后，我通过窗口句柄杀死了这个过程。

uint processID;

GetWindowThreadProcessId((IntPtr)hWnd, out processID);

if (processID == 0) return false;

try
{
Process.GetProcessById((int)processID).Kill();
}
catch (ArgumentException)
{
return false;
}
catch (Win32Exception)
{
return false;
}
catch (NotSupportedException)
{
return false;
}
catch (InvalidOperationException)
{
return false;
}

return true;

}

为了使上述工作正常进行，您还需要确保包含win32 API。
