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

The regex method is superior I think, but if you wanted to use the humble substring

string input= "my name is (Jayne C)";
int start = input.IndexOf("(");
int stop = input.IndexOf(")");
string output = input.Substring(start+1, stop - start - 1);

or

string input = "my name is (Jayne C)";
string output  = input.Substring(input.IndexOf("(") +1, input.IndexOf(")")- input.IndexOf("(")- 1);
