字符串末尾“ /”的C＃正则表达式

Question

I have a collection of url's and i need to write regular expression to filter needed content.

/data/43492-someText/"

/data/221639-anotherText/"

/data/116345-differentText/"

/data/6630-boooring/"

/data/220742-foo/"

What i need is only strings without /" on the end, so

/data/220742-foo

My Regular Expression looks like this:

@"/data/[0-9]{1,10}-.*""\s"

Note: I dont want to do this with string replace, because of some limitations on my project.

Answer 1

If that (string not ending in / ) is the only requirement, then use something like this:

var desiredUrls = urls.Where(url => !url.EndsWith("/\""))

I initially read the question as a desire to filter urls but I can see how it could be a mapping question.

var withoutSuffix = urls.Select(url => url.TrimEnd("/\"".ToCharArray());

Answer 2

I think Regular Expressions are kind of overkill for what you're trying to do.

Anyways you can use something like this :

@"/data/[0-9]{1,10}-[^/]+"

Answer 3

您可以使用TrimEnd从字符串末尾删除字符：

s.TrimEnd('/', '"')

Answer 4

You could use something like:

(/data/[0-9]{1,10}-.+)/

And the string without the trailing / will be in the first capture group.
