When I want to allow the caller to pass in one or more values as an array, is it more performant to pass it in as a normal array or use the params keyword? Well, both approaches show very similar speeds. Below are examples for comparison.

private void SomeMethod(int count, string[] args)

or

private void SomeMethod(int count, params string[] args)

I recommend using params since it’s easier to use when calling the function.
