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

While there are times when you will want to use a non-generic collection (think caching, for instance), you almost always have collections of homogenous objects not heterogenous objects. For a homogenous collection, even if it is a collection of variants of base type or interface, it's always better to use generics. This will save you from having to cast the result as the real type before you can use it. Using generics makes your code more efficient and readable because you can omit the code to do the cast.
