I figured it out.
我想到了。

In Unix this is known as the basename, a quick google came up with this link for a C# version. I'm sure there are others ...
在 Unix 中这被称为 basename，一个快速的谷歌想出了这个C# 版本的链接。我确定还有其他人......

Try
尝试
System.IO.Path.GetFileName("C:\temp\foo\bar");
回答by Wim Haanstra
if the answers above do not satisfy your needs, why not just substring the string from the last .
如果上面的答案不能满足您的需求，为什么不从最后一个 .
string dirName = originalDirName.Substring(originalDirName.LastIndexOf("\") + 1);
sure, you should do some checking if the originalDirName does not end on a \ and if the originalDirName is longer than zero and actually contains \ characters.
当然，您应该检查 originalDirName 是否不以 \ 结尾，以及 originalDirName 是否长于零并且实际上包含 \ 字符。

I can think of 4 ways instantly
我能立刻想到4种方法
1
1
- If the string ends with a slash remove it
- Use Path.GetFilename (or numerous other System.IO methods)
- 如果字符串以斜杠结尾，则将其删除
- 使用 Path.GetFilename（或许多其他 System.IO 方法）
2
2
- Split the string on slashes into an array
- Get the last index of the array
- 将斜杠上的字符串拆分为数组
- 获取数组的最后一个索引
3
3
- Create a Uri class with it in the constructor
- Use the Segments property
- 在构造函数中用它创建一个 Uri 类
- 使用 Segments 属性
4
4
- The linq way someone mentioned above
- 上面提到的linq方式

It looks like a bunch of people have withdrawn their answers, which is possibly a shame.
看起来一堆人撤回了他们的答案，这可能是一种耻辱。
This one's got to be worth stating, only for the "teach a man to fish" quality of it - it's short, elegant and made of two separate things that, once learned, can be re-applied to other problems.
值得一提的是，这只是因为它的“教人钓鱼”的品质——它简短、优雅，由两个独立的东西组成，一旦学会，就可以重新应用于其他问题。
string lastPiece = wholePath.Split('\').Last();
Lastwill throw if the list is empty.
Last如果列表为空，将抛出。

Try this
尝试这个
string DirName = System.IO.Directory.GetParent(@"C:\temp\foo\bar\").Name;
回答by Norbert B.
Just use:
只需使用：
string dirname = new DirectoryInfo(@"C:\temp\foo\bar\").Name;
According to MSDN this returns the name of the directory, not the full path.
根据 MSDN，这将返回目录的名称，而不是完整路径。
Hope this helps.........
希望这可以帮助.........

The simplest way to do this withoutcreating a new DirectoryInfoinstance is to use the Path.GetFileNamestatic method. This is located in System.IO.
在不创建新DirectoryInfo实例的情况下执行此操作的最简单方法是使用Path.GetFileName静态方法。它位于 System.IO 中。
using System.IO;
string lastFolderName = Path.GetFileName(@"C:\Folder1\Folder2");
The variable would be set to "Folder2".
该变量将设置为“Folder2”。
This is quite a bit more efficientthat creating a new instance of the DirectoryInfo class!
这比创建 DirectoryInfo 类的新实例要高效得多！

string dirname = new DirectoryInfo(path).Name;
Console.WriteLine(dirname);
