Is there a built-in function to repeat a string or char in .NET?

Is there a function in C# that returns x times of a given char or string? Or must I code it myself?

The best solution is the built in string function:

 Strings.StrDup(2, "a")

For strings you should indeed use Kirk's solution:

string.Join("", Enumerable.Repeat("ab", 2));

However for chars you might as well use the built-in (more efficient) string constructor:

new string('a', 2); // returns aa

string.Join("", Enumerable.Repeat("ab", 2));

Returns

"abab"

And

string.Join("", Enumerable.Repeat('a', 2))

Returns

"aa"
