C#中 Stack.Contains()方法以及示例
C#Stack.Contains()方法
Stack.Contains()方法用于检查堆栈中是否存在元素/对象,如果堆栈中存在对象/元素,则返回true,否则返回false。
语法:
bool Stack.Clone(Object);
参数:Object-要检查的对象,是否存在于堆栈中。
返回值:bool–如果堆栈中存在对象,则返回true,否则返回false。
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);
checking elements:
stk.Contains(100);
stk.Contains(800);
Output:
true
falseC#使用Stack.Contains()方法检查堆栈中是否存在对象/元素的示例
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);
//打印堆栈元素
Console.WriteLine("Stack elements are...");
printStack(stk);
//检查要素
if (stk.Contains(100) == true)
Console.WriteLine("100 exists in the stack");
else
Console.WriteLine("100 does not exist in the stack");
if (stk.Contains(800) == true)
Console.WriteLine("800 exists in the stack");
else
Console.WriteLine("800 does not exist in the stack");
//按ENTER退出
Console.ReadLine();
}
}
}输出结果
Stack elements are... 500 400 300 200 100 100 exists in the stack 800 does not exist in the stack
