C#: System.Object vs Generics

Question

I\'m having a hard time understanding when to use Object (boxing/unboxing) vs when to use generics.

For example:

public class Stack 
{
    int positi         


        

Answer 1

Use generics when you want your structure to handle a single type. For example, if you wanted a collection of strings you would want to instantiate a strongly typed List of strings like so:

List myStrings = new List();

If you want it to handle multiple types you can do without generics but you will incur a small performance hit for boxing/unboxing operations.
