用 C# 获取栈中包含的元素数量
若要获取栈中包含的元素数量,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"); Console.WriteLine("Count of elements = "+stack.Count); Console.WriteLine("Elements in Stack..."); foreach (string res in stack){ Console.WriteLine(res); } stack.Clear(); Console.Write("Count of elements (updated) = "+stack.Count); } }
输出
这将产生以下输出 −
Count of elements = 8 Elements in Stack... H G F E D C B A Count of elements (updated) = 0
示例
我们来看另一个示例 −
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("Elements in Stack..."); foreach (int res in stack){ Console.WriteLine(res); } } }
输出
这将产生以下输出 −
Count of elements = 10 Elements in Stack... 100 90 80 70 60 50 40 30 20 10
