用 C# 获取 Stack 顶部的对象
要获得 Stack 顶部的对象,代码如下 −
示例
using System; using System.Collections.Generic; public class Demo { public static void Main() { Stack<string> stack = new Stack<string>(); stack.Push("A"); stack.Push("B"); stack.Push("C"); stack.Push("D"); stack.Push("E"); stack.Push("F"); stack.Push("G"); stack.Push("H"); stack.Push("I"); stack.Push("J"); Console.WriteLine("Count of elements = "+stack.Count); Console.WriteLine("Element at the top of stack = " + stack.Peek()); } }
输出
这将产生以下输出 −
Count of elements = 10 Element at the top of stack = J Count of elements = 10
示例
让我们看看另一个示例 −
using System; using System.Collections.Generic; public class Demo { public static void Main() { Stack<int> stack = new Stack<int>(); stack.Push(10); stack.Push(20); stack.Push(30); stack.Push(40); stack.Push(50); stack.Push(60); stack.Push(70); stack.Push(80); stack.Push(90); stack.Push(100); Console.WriteLine("Count of elements = "+stack.Count); Console.WriteLine("Element at the top of stack = " + stack.Peek()); Console.WriteLine("Element at the top of stack = " + stack.Peek()); } }
输出
这将产生以下输出 −
Count of elements = 10 Element at the top of stack = 100 Element at the top of stack = 100
