c#泛形——stack

定义自己的stack
using System;using System.Collections.Generic;using System.Web;public class TStack<T>{ private Node first = null; public bool Empty { get { return (first == null); } } public T Pop() { if (first == null) throw new Exception("Can't Pop from an empty Stack."); else { T temp = first.Value; first = first.Next; return temp; } } public void Push(T item) { first = new Node(item, first); } private class Node { public Node Next; public T Value; public Node(T value) : this(value, null) { } public Node(T value, Node next) { Next = next; Value = value; } }}

使用
TStack<int> stack = new TStack<int>(); stack.Push(1); stack.Push(2); stack.Push(3); int i = stack.Pop();

c#的stack。当然可以如ArraryList中使用Object，要拆装箱影响性能，而且编译时无法发现类型错误。
