问题描述

如何知道给定的目录是否是根驱动器？

How can I know if a given directory is a root drive?

（除了检查其路径是否等于A：，B：， C：等）

(aside from checking if its path equals to "A:", "B:", "C:", etc.)

推荐答案

检查DirectoryInfo.Parent是否为空

Check if DirectoryInfo.Parent is null or not

DirectoryInfo d = new DirectoryInfo("");
if(d.Parent == null) { IsRoot = true; }

您还可以使用DirectoryInfo.Root获取根;

you can also get the root by using DirectoryInfo.Root;
