C++(18):获取windows下文件的创建/修改/访问时间

    DWORD dw = GetLastError();

	snprintf(szBuf, sizeof(szBuf), "%s failed: GetLastError returned %u\n",lpszFunction, dw);

    MessageBox(NULL, szBuf, "Error", MB_OK);
    ExitProcess(dw);

BOOL GetFileTime(HANDLE hFile, LPSTR lpszCreationTime, LPSTR lpszLastAccessTime, LPSTR lpszLastWriteTime)

    SystemTimeToTzSpecificLocalTime(NULL, &stUTC1, &stLocal1);
    SystemTimeToTzSpecificLocalTime(NULL, &stUTC2, &stLocal2);

    // ---------> Show the  date and time.
    wsprintf(lpszCreationTime, "创建时间:\t%02d/%02d/%d  %02d:%02d",
        stLocal1.wDay, stLocal1.wMonth, stLocal1.wYear,
        stLocal1.wHour, stLocal1.wMinute);
    wsprintf(lpszLastAccessTime, "最后访问时间:\t%02d/%02d/%d  %02d:%02d",

//----------------------------------------------------------------
int main()
{

    HANDLE hFile;
    TCHAR szCreationTime[30], szLastAccessTime[30], szLastWriteTime[30];
    hFile = CreateFile("D:/test.txt", 0, FILE_SHARE_READ, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);
    GetFileTime(hFile, szCreationTime, szLastAccessTime, szLastWriteTime);
    if (hFile == INVALID_HANDLE_VALUE){
        error("GetLastWriteTime()");
        return 0;
    }
    printf("%s\n%s\n%s\n", szCreationTime, szLastAccessTime, szLastWriteTime);
    CloseHandle(hFile);
    system("pause");

    return 0;
}

调用就在main函数中，需要访问的文件就是 CreateFile() 函数的第一个参数

 

需要强调一下，vs中编译的时候需要在项目属性中，将字符编码改为 "多字节字符集"，默认的是unicode
