如何设置一个文件的修改时间编程在Windows？

How do I set the modification time of a file programmatically in Windows?

推荐答案

Windows（或标准的CRT，无论如何）具有相同的出现UTimes 家庭的函数，UNIX了。

Windows (or the standard CRT, anyhow) has the same utimes family of functions that UNIX has.

struct _utimebuf t;
t.tma = 1265140799;  // party like it's 1999
t.tmm = 1265140799;
_utime(fn, &t);

使用Win32函数， FILE_BASIC_INFO 可使用的SetFileInformationByHandle 。

FILE_BASIC_INFO b;
b.CreationTime.QuadPart = 1265140799;
b.LastAccessTime.QuadPart = 1265140799;
b.LastWriteTime.QuadPart = 1265140799;
b.ChangeTime.QuadPart = 1265140799;
b.FileAttributes = GetFileAttributes(fn);
SetFileInformationByHandle(h, FileBasicInfo, &b, sizeof(b));
