Question

I have this object of mine named Rooms can i batch initialized them using linq instead of using this kind of code?

List<Rooms> listOfRooms = new List<Rooms>();
foreach(var room in listOfRooms)
{
  room = new Rooms();
}

Answer 1

var listOfRooms = Enumerable.Range(0, 10).Select(p => new Rooms()).ToList();

This is a solution for creating a List with 10 Rooms.

Note that in the Select you have access to the index (0…9) (called p). You can use to do fancy logic and initialized Rooms with specific values.

As suggested by Mustafin, there is an “hybrid” Linq expression that can be used:

var listOfRooms = (from p in Enumerable.Range(0, 10) select new Rooms()).ToList();

I don’t like this form because it “mixes” the two “styles” of Linq.
