Way to fill List<> with elements

Question

I have in my code

List<BookedReelsState> retVal = new List<BookedReelsState>(somesize);

Match later in the code if some condition works I need to fill this entire List with same value.

Of course I can do it via foreach loop and set values , Is there more elegant way to do so ? I just to learn something new here .

Answer 1

retVal.AddRange(Enumerable.Repeat(value, somesize));
