Question

Short question, but can’t make it work. I have a string:

COMPANY NAME - username (Name Surname).

What kind of regex will give me username (without spaces) from between - and ( in such example?

It’s ASP.NET C# if it makes any difference. Thanks in advance !

EDIT :
The company name is a string with possible spaces. Username is without spaces. The characters - and ( are present only in these 2 places. I thought it was 100% obvious since I gave such example.

Answer 1

var match = Regex.Match(
    "COMPANY - ltd (NAME) - username (Name Surname)", 
    @"^.* - (.*?) \(.*\)$"
);
var username = match.Groups[1].Value;

If your line ends with a . then the Regex is @"^.* - (.*?) \(.*\)\.$"

Through the use of .*? (the lazy quantifier) this Regex is quite resistant to strange “things” like the one I’m using as a test.

Link with tests. Pass over each row to see the capture group.
