Get contents after last slash
提问by john cs
I have strings that have a directory in the following format:
我的字符串具有以下格式的目录：
C://hello//world
C://你好//世界
How would i extract everything after the last / character (world)?
我将如何提取最后一个 / 字符（世界）之后的所有内容？
采纳答案by Simon Whitehead
string path = "C://hello//world";
int pos = path.LastIndexOf("/") + 1;
Console.WriteLine(path.Substring(pos, path.Length - pos)); // prints "world"
The LastIndexOfmethod performs the same as IndexOf.. but from the end of the string.
该LastIndexOf方法的执行与IndexOf..相同，但从字符串的末尾开始。

I would suggest looking at the System.IOnamespace as it seems that you might want to use that. There is DirectoryInfo and FileInfo that might be of use here, also. Specifically DirectoryInfo's Name property
我建议查看System.IO命名空间，因为您可能想要使用它。还有 DirectoryInfo 和 FileInfo 也可能在这里有用。特别是DirectoryInfo 的 Name 属性
var directoryName = new DirectoryInfo(path).Name;
