.NET2.0 Base Class Library 系列（四）泛型 Generics Type

1. introduction to Generics
   Generic classes and methods combine reusability, type safety and efficiency in a way that their non-generic counterparts cannot. Generics are most commonly used with collections and the methods that operate on them. Because no casting needed,no boxing needed.
2. Benefits of Generics
   By creating a generic class, you can create a collection that is type-safe at compile-time.
   
   1using System.Collections.Generic;
   2
   3public List<int> myList = new List<int>();
   4
   Use generic types to maximize code reuse, type safety, and performance.
