文件的最后写入时间
问题描述：
我很好奇，但无法通过谷歌搜索找到答案.文件LastWriteTime的实际时间是多少?是在第一次写入文件时还是在文件写入完成时?谢谢.
I am curious and I haven''t been able to find the answer by googling. What is the actual time of a files LastWriteTime? Is it when the file is first being written or is it when the file finishes being written? Thank you.
答
如果有内存可用，则在关闭文件时会更新时间.只需用几行代码即可确认.
If memory serves the time is updated when the file is closed. This should be fairly easy to confirm with a few lines of code.
根据GetFileTime()的文档 ^ ] Windows会同时记录创建时间和文件最后写入的时间.选择一个对您有用的.
According to the documentation for GetFileTime() [^] Windows records *both* the creation time *and* the time the file was last written to. Pick the one that''s useful to you.
