问题描述
我正在制作一个脚本,找到路径中的第二个文件夹,我该怎么做?
I am making a script that finds what the 2nd folder in the path is, how would I do this?
dirA
dirB / C ----我需要dirB
indirB - dirD / E
indirE - 文件
dirA
dirB/C ---- I need dirB
indirB - dirD/E
indirE - The file
我需要找到文件夹的名称在第二级文件路径(我用星星标记)。
I need to find the name of the folder in the 2nd level that paths to the file (I marked it with stars).
我将如何找到这个
推荐答案
此扩展程序如何:
public static class StringExtensions
{
public static String PathLevel(this String path, int level)
{
if (path == null) throw new ArgumentException("Path must not be null", "path");
if (level < 0) throw new ArgumentException("Level must be >= 0", "level");
var levels = path.Split(Path.DirectorySeparatorChar);
return levels.Length > level ? levels[level] : null;
}
}
测试:
var path = @"C:\Temp\Level2\Level3\Level4\File.txt";
var secondLevel = path.PathLevel(2); // => "Level2"
它将路径分割为 DirectorySeparatorChar
到串[]
。
你想要第二级(第三个元素),这返回Level2。请注意,第一个元素是 C:
。
It splits the path by DirectorySeparatorChar
to a String[]
.
You wanted the second level(the third element), this returns "Level2". Note that the first element is C:
.
