I have three classes (Street, Shop , StartingPoint) inherited from class Event. I created ListList<Event> eventList = new List<Event>(); and added them in List : eventList.Add(new Street()); eventList.Add(new Shop());etc. How can i acces specific class ? For example i want working only with Shop. How can i acces it ?

Like Selman22 said you can use eventList.OfType<Shop>().First(); to access on the first shop in your list. If you want to have a specified shop you have to work with the name of the shop or the street or whatever.

This will then look like;

eventList.OfType<Shop>().FirstOrDefault(x => x.StreetName == "WallStreet");

That returns you the Shop where the streetname of the Shop is like "WallStreet"

With indexer ?

eventList[index]

Or LINQ ?

eventList.OfType<Shop>().First();

OfType<Shop>() will return all Shops.If you want single Shop you can use First.
