使用Directory.GetFiles在C＃正则表达式？ [英] Using Directory.GetFiles with a regex in C#?

问题描述

我有这样的代码：

string[] files = Directory.GetFiles(path, "......", SearchOption.AllDirectories)

我要的是仅返回不与<$开头的文件C $ç>点_ 和 T _ 并具有扩展名PNG或JPG或GIF。我会怎么做呢？

What I want is to return only files which do NOT start with p_ and t_ and have the extension png or jpg or gif. How would I do this?

推荐答案

Directory.GetFiles 不支持正则表达式默认情况下，你可以做的就是正则表达式您的文件列表进行过滤。看看此房源：

Directory.GetFiles doesn't support RegEx by default, what you can do is to filter by RegEx on your file list. Take a look at this listing:

Regex reg = new Regex(@"^^(?!p_|t_).*");

var files = Directory.GetFiles(yourPath, "*.png; *.jpg; *.gif")
                     .Where(path => reg.IsMatch(path))
                     .ToList();
