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
