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?

Method 1

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

Returns

"abab"

And

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

Returns

"aa"

Method 2

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

returns

“abab”

Method 3

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

Method 4

new String('*', 5)

See Rosetta Code.

Method 5

The best solution is the built in string function:

 Strings.StrDup(2, "a")
