一点 LINQ 应该让你走上正确的道路。



这是在C＃所以你需要做一点翻译，但它会给你文件按创建日期的顺序排列。您可以输入 FirstOrDefault（）并获取最旧的文件

A little bit of LINQ should get you on the right path.

This is in C# so you will need to do a little translating, but it will give you the files in order of creation date. You could probably throw in a FirstOrDefault() and just get the oldest file

FileInfo[] files = info.GetFiles().OrderBy(p => p.CreationTime);
