推荐答案

由于.NET具有自动垃圾收集功能，因此收集器有时可能需要一些时间才能识别出它已经完成了...

Because .NET has automatic garbage collection it can sometimes take some time for the collector to recognize that it''s finished...

Marshal.ReleaseComObject(...);

这可以帮助加快速度并主动命令它释放excel(或任何其他com对象)

看看这个:

this can help speed this up and actively order it to release excel (or any other com object)
