在队列的开头获取对象– C#中的窥视操作
要在队列的开始处获取对象，代码如下-
示例
using System;
using System.Collections.Generic;
public class Demo {
public static void Main() {
Queue<string> queue = new Queue<string>();
queue.Enqueue("A");
queue.Enqueue("B");
queue.Enqueue("C");
queue.Enqueue("D");
queue.Enqueue("E");
queue.Enqueue("F");
queue.Enqueue("G");
Console.WriteLine("Count of elements = "+queue.Count);
Console.WriteLine("Element at the beginning of queue = " + queue.Peek());
}
}输出结果
这将产生以下输出-
Count of elements = 7 Element at the beginning of queue = A
示例
让我们看另一个例子-
using System;
using System.Collections.Generic;
public class Demo {
public static void Main() {
Queue<string> queue = new Queue<string>();
queue.Enqueue("A");
queue.Enqueue("B");
queue.Enqueue("C");
queue.Enqueue("D");
queue.Enqueue("E");
queue.Enqueue("F");
queue.Enqueue("G");
Console.WriteLine("Count of elements = "+queue.Count);
Console.WriteLine("Element at the beginning of queue = " + queue.Peek());
queue.Enqueue("H");
queue.Enqueue("I");
queue.Enqueue("J");
Console.WriteLine("Count of elements = "+queue.Count);
Console.WriteLine("Element at the beginning of queue = " + queue.Peek());
}
}输出结果
这将产生以下输出-
Count of elements = 7 Element at the beginning of queue = A Count of elements = 10 Element at the beginning of queue = A
