using System; //using System.Collections.Generic; using System.Text; using System.Collections;   namespace StackHelper {     class StackHelper     {         private Stack list;         public Stack List         {             set { list = value; }             get { return list; }         }         public StackHelper()         {             list = new Stack();//注意：不是list=new StackHelper()             Console.WriteLine("---------Stack-----------");         }         //压入一个元素         public void Add(object o)         {             list.Push(o);             Console.WriteLine("压入\t元素：{0}",o);         }         //删除栈顶元素         public void Remove()         {             list.Pop();             Console.WriteLine("弹出栈顶元素");         }         //取出栈顶元素         public void GetValue()         {             list.Peek();             Console.WriteLine("取出栈顶元素的值");         }         //使用foreach进行遍历         public void GetValues()         {             Console.WriteLine("遍历");             foreach (object o in list)             {                 Console.WriteLine(string.Format("\t元素的值：{0}",o));             }         }         //得到Stack的信息         public void GetInfo()         {             Console.WriteLine(string.Format("信息\t元素总数：{0}",list.Count));         }     } }

using System; using System.Collections.Generic; using System.Text; using System.Collections;   namespace StackHelper {     class Program     {         static void Main(string[] args)         {             StackHelper list=new StackHelper();             list.Add("a");             list.Add("b");             list.Add("c");             list.GetInfo();             list.GetValues();             list.GetValue();             list.GetValues();             list.GetInfo();             list.Remove();             list.GetValues();             list.GetInfo();         }     } }

注意：Pop ()和Peek()方法的区别。Pop()取出栈顶元素，栈顶元素被弹出Stack；Peek()读得栈顶元素，但站定元素没有被弹出Stack。
