Stack.Peek()方法用于从堆栈中删除所有对象。
语法:
void Stack.Clear();
参数:无
返回值: void –不返回任何内容。
示例
declare and initialize a stack: Stack stk = new Stack(); insertting elements: stk.Push(100); stk.Push(200); stk.Push(300); stk.Push(400); stk.Push(500); clearing all objects/elements: stk.Clear(); Output: None
using System; using System.Text; using System.Collections; namespace Test { class Program { //打印堆栈元素的功能 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); Console.WriteLine("Total number of objects in the stack: " + stk.Count); //打印堆栈元素 Console.WriteLine("Stack elements are..."); printStack(stk); //清除所有对象/元素 stk.Clear(); Console.WriteLine("Total number of objects in the stack: " + stk.Count); //按ENTER退出 Console.ReadLine(); } } }
输出结果
Total number of objects in the stack: 5 Stack elements are... 500 400 300 200 100 Total number of objects in the stack: 0
