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);

Answer 1

string line = new String('x', 10).Replace("x", "-.");

Answer 2

var result = String.Join("", Enumerable.Repeat("-.", 10));

Answer 3

A slight variation on the answer by Bala R

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