using System;

static void printStack(Stack s)
{
foreach (Object obj in s)
{
Console.Write(obj + " ");
}
Console.WriteLine();
}
static void Main(string[] args)
{
//声明并初始化堆栈
Stack stk = new Stack();
//插入元素
stk.Push(100);
stk.Push(200);
stk.Push(300);
stk.Push(400);
stk.Push(500);
//打印堆栈元素
Console.WriteLine("Stack elements before popping are...");
printStack(stk);
//弹出堆栈元素
object item = 0;
item = stk.Pop();
Console.WriteLine(item + " is popped");
item = stk.Pop();
Console.WriteLine(item + " is popped");
item = stk.Pop();
Console.WriteLine(item + " is popped");
//打印堆栈元素
Console.WriteLine("Stack elements after popping are...");
printStack(stk);
//按ENTER退出
Console.ReadLine();
}
}
}输出结果
Stack elements before popping are... 500 400 300 200 100 500 is popped 400 is popped 300 is popped Stack elements after popping are... 200 100
