Is there an easy way to return a string repeated X number of times?

If you're using .NET 4.0, you could use string.Concat together with Enumerable.Repeat.

int N = 5; // or whatever
Console.WriteLine(string.Concat(Enumerable.Repeat(indent, N)));

Otherwise I'd go with something like Adam's answer.

The reason I generally wouldn't advise using Andrey's answer is simply that the ToArray() call introduces superfluous overhead that is avoided with the StringBuilder approach suggested by Adam. That said, at least it works without requiring .NET 4.0; and it's quick and easy (and isn't going to kill you if efficiency isn't too much of a concern).

If you only intend to repeat the same character you can use the string constructor that accepts a char and the number of times to repeat it new String(char c, int count).

For example, to repeat a dash five times:

string result = new String('-', 5);
Output: -----
