How to initialize a List to a given size (as opposed to capacity)?

Question

.NET offers a generic list container whose performance is almost identical (see Performance of Arrays vs. Lists question). However they are quite different in initialization

Answer 1

If you want to initialize the list with N elements of some fixed value:

public List InitList(int count, T initValue)
{
  return Enumerable.Repeat(initValue, count).ToList();
}
