How to return Generic?

Question

C++ / C#

Tell me how to return from a generic int overload method? I can not understand...

public static IEnumerable<int> SomeMethod<T>(this IEnumerable<T> list, Func<T, int> someAction, int percentline)
...
return???

Answer 1

Judging by what parameters you have passed to the method, then you need the Select method.
What is percentline for, by the way? How is it used?

Answer 2

foreach (var item in list)
{
     yield return someAction(item);
}
