按最后一个分隔符拆分字符

Question

What I have is a giant text file that contains a bunch of strings that are split by \\ . The problem for me is there can be 5 \\ or 4 \\ or 3 \\ .

What I need to to pull the last \\ no matter how many of them there are. Any help is appreciated.

Examples:

I\need\this
I\want\line\this
Hello\give\me\all\this

I need the word this for example, but obviously it's not just the word this .

Answer 1

string last = inputString.Substring(inputString.LastIndexOf('\\') + 1);

Answer 2

string myString = inputString.Split('\\').Last();

Answer 3

差点忘了这个（尽管有点厚脸皮）：

string result = Path.GetFilename(input);
