How to repeat a set of characters

Question

I'd like to repeat a set of characters multiple times. I know how to do it with a single character:

string line = new string('x', 10);

But what I'd like would be something more like this:

string line = new string("-.", 10);

which would result in: -.-.-.-.-.-.-.-.-.-.

I know the string constructor can't do it, but is there some other way within the BCL? Other suggestions?

Thanks!

Have never seen the Enumerable class. Awesome +1 – Ryan Bennett Sep 29 '11 at 18:05
@RyanBennett, you mean you never used LINQ? :) – Emond Erno Sep 29 '11 at 18:13
Not like that - not sure how I was able to go three years and overlook an entire class... – Ryan Bennett Sep 29 '11 at 18:41
Thanks! I also didn't know about the Enumerable class. Very nice. – Greg McGuffey Sep 29 '11 at 18:44

A slight variation on the answer by Bala R

var s = String.Concat(Enumerable.Repeat("-.", 10));

Nice way, if you can not access the Enumerable class (like in WinWrapBasic) – Alexander Taubenkorb Jan 19 '15 at 08:43
