in function to repeat string or char in .net?

2018-06-06 19:48:07

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

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

Returns

"abab"

And

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

Returns

"aa"

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

returns

"abab"

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
