C# Inheritance & setting up a list of objects


I have a question on the best way to setup a list of objects.

Say I have a base class called Animals. For example say I have a list that contains 4 Animals (could be lots more than but this is just a simple example).

I also have four other objects that all inherit from the Animals class. Lets call them Dog, Lion, Monkey & Cat.

At run time I have no idea which of the four objects will need to be intialised, it could be 4 dogs or 2 monkeys, 1 cat & 1 lion etc.

Currently I am using a if statement block which works but was wondering if there was a better way of doing this.

for(int i =0 ; i < AnimalsSelected.Lenght; i++)
     if(AnimalsSelected[i].Name == "Dog")
         Animals[i] = new Dog();
     elseif (AnimalsSelected[i].Name == "Lion")
         Animals[i] = new Lion();
     // etc

You can use a switch case statement
   case "Dog":
      Animals[i] = new Dog();
   case "Lion":
      Animals[i] = new Lion();
       // Some kind of error (this is like the else case in an if, elseif, else block).
