检查堆栈中是否包含C#中的元素
要检查Stack是否具有元素，请使用C#Contains()方法。以下是代码-
示例
using System;
using System.Collections.Generic;
public class Demo {
public static void Main(){
Stack<int> stack = new Stack<int>();
stack.Push(100);
stack.Push(150);
stack.Push(175);
stack.Push(200);
stack.Push(225);
stack.Push(250);
stack.Push(300);
stack.Push(400);
stack.Push(450);
stack.Push(500);
Console.WriteLine("堆栈中的元素：");
foreach(var val in stack){
Console.WriteLine(val);
}
Console.WriteLine("Count of elements in the Stack = "+stack.Count);
Console.WriteLine("Does Stack has the element 400?= "+stack.Contains(400));
}
}输出结果
这将产生以下输出-
堆栈中的元素： 500 450 400 300 250 225 200 175 150 100 Count of elements in the Stack = 10 Does Stack has the element40400?= True
示例
让我们看另一个例子-
using System;
using System.Collections.Generic;
public class Demo {
public static void Main(){
Stack<string> stack = new Stack<string>();
stack.Push("Steve");
stack.Push("Gary");
stack.Push("Stephen");
stack.Push("Nathan");
stack.Push("Katie");
stack.Push("Andy");
stack.Push("David");
stack.Push("Amy");
Console.WriteLine("堆栈中的元素：");
foreach(var val in stack){
Console.WriteLine(val);
}
Console.WriteLine("Count of elements in the Stack = "+stack.Count);
Console.WriteLine("Does Stack has the element 400?= "+stack.Contains("Michael"));
}
}输出结果
这将产生以下输出-
堆栈中的元素： Amy David Andy Katie Nathan Stephen Gary Steve Count of elements in the Stack = 8 Does Stack has the element 400?= False
