如何检查目录1是否为dir2的子目录，反之亦然 [英] How to check if directory 1 is a subdirectory of dir2 and vice versa

问题描述

检查目录1是目录2的子目录，反之亦然吗？

我检查了Path和DirectoryInfo辅助类，但没有发现系统 - 准备好这个功能。我认为这会在某个地方。

你们有什么想法找到这个吗？

我试着自己写一个支票，但是比起我预期的更复杂一些。

解决方案

你可以将directory2与directory1的 父属财产 DirectoryInfo d2 = new DirectoryInfo（@C：\Program Files\MyApp\Images）;

if（d2.Parent.FullName == d1.FullName）
{
Console.WriteLine（Sub directory）;
}

What is an easy way to check if directory 1 is a subdirectory of directory 2 and vice versa?

I checked the Path and DirectoryInfo helperclasses but found no system-ready function for this. I thought it would be in there somewhere.

Do you guys have an idea where to find this?

I tried writing a check myself, but it's more complicated than I had anticipated when I started.

解决方案

You can compare directory2 to directory1's Parent property when using a DirectoryInfo in both cases.

DirectoryInfo d1 = new DirectoryInfo(@"C:\Program Files\MyApp");
DirectoryInfo d2 = new DirectoryInfo(@"C:\Program Files\MyApp\Images");

if(d2.Parent.FullName == d1.FullName)
{
    Console.WriteLine ("Sub directory");
}
