要将对象添加到队列的末尾,代码如下-
using System; using System.Collections.Generic; public class Demo { public static void Main(){ Queue<string> queue = new Queue<string>(); queue.Enqueue("Electronics"); queue.Enqueue("Accessories"); queue.Enqueue("Toys"); queue.Enqueue("Books"); queue.Enqueue("Furniture"); queue.Enqueue("Clothing"); queue.Enqueue("Footwear"); queue.Enqueue("Cookware"); queue.Enqueue("Pet Supplies"); Console.WriteLine("Elements in the Queue..."); foreach(var element in queue){ Console.WriteLine(element); } Console.WriteLine("Do the queue has the element Books? = "+queue.Contains("Books")); } }
输出结果
这将产生以下输出-
Elements in the Queue... Electronics Accessories Toys Books Furniture Clothing Footwear Cookware Pet Supplies Do the queue has the element Books? = True
现在让我们来看另一个示例-
using System; using System.Collections.Generic; public class Demo { public static void Main(){ Queue<string> queue = new Queue<string>(); queue.Enqueue("Gary"); queue.Enqueue("Jack"); queue.Enqueue("Ryan"); queue.Enqueue("Kevin"); queue.Enqueue("Mark"); queue.Enqueue("Jack"); queue.Enqueue("Ryan"); queue.Enqueue("Kevin"); Console.Write("Count of elements = "); Console.WriteLine(queue.Count); queue.Clear(); Console.Write("Count of elements (updated) = "); Console.WriteLine(queue.Count); } }
输出结果
这将产生以下输出-
Count of elements = 8 Count of elements (updated) = 0
