How do I extract text that lies between parentheses (round brackets)?

Question

I have a string User name (sales) and I want to extract the text between the brackets, how would I do this?

I suspect sub-string but I can\'t work out

Answer 1

Assuming that you only have one pair of parenthesis.

string s = "User name (sales)";
int start = s.IndexOf("(") + 1;
int end = s.IndexOf(")", start);
string result = s.Substring(start, end - start);
