Question

因此，我们有一些（或更多，没有人知道）应用程序编写的应用程序已经离开，这些应用程序访问存储在此开发人员旧PC上的Microsoft Access数据库，而后者又从我们的生产SQL数据库中读取。现在要跟踪所有这些程序，以及它们运行的时间，我想保留一个文件访问时间的日志，这可能吗？显然，如果我读取访问时间，我会修改它。我们不能依赖修改的时间，因为一些Access数据库只是SQL数据库的链接表。

喜欢在C＃中这样做，但没关系。只需要追踪到哪里运行，一旦我找到它们，就可以修改它们。

感谢。

    while(Console.Read()!='q');
}

// Define the event handlers.
private static void OnChanged(object source, FileSystemEventArgs e)
{
    // Specify what is done when a file is changed, created, or deleted.
   Console.WriteLine("File: " +  e.FullPath + " " + e.ChangeType);
}

private static void OnRenamed(object source, RenamedEventArgs e)
{
    // Specify what is done when a file is renamed.
    Console.WriteLine("File: {0} renamed to {1}", e.OldFullPath, e.FullPath);
}
