How does the List class work? (System.Collections.Generic)

Question

An array is defined with a specific size. But if I want a array, which grows dynamically, I use the List class (from namespace System.Collections.Generic). But how does this class work? How does the list grow dynamically?

Answer 1

Let's say our list is for strings then it will be
List <string> ourList = new List <string>();
ourList.Add ("value1");
ourList.Add ("value2");
and so on ...

when you need to access any item you can do that using index :
string myValue= ourList [0];
