C#中的Queue.Clear方法
C#中的Queue.Clear()方法用于从Queue中清除所有对象。
语法
语法如下-
public virtual void Clear ();
示例
现在让我们看一个例子-
using System;
using System.Collections.Generic;
public class Demo {
public static void Main() {
Queue<int> queue = new Queue<int>();
queue.Enqueue(100);
queue.Enqueue(200);
queue.Enqueue(300);
queue.Enqueue(400);
queue.Enqueue(500);
queue.Enqueue(600);
queue.Enqueue(700);
queue.Enqueue(800);
queue.Enqueue(900);
queue.Enqueue(1000);
Console.WriteLine("Queue...");
foreach(int i in queue) {
Console.WriteLine(i);
}
Console.WriteLine("Count of elements in the Queue = "+queue.Count);
queue.Clear();
Console.WriteLine("Count of elements in the Queue [Updated] = "+queue.Count);
}
}输出结果
这将产生以下输出-
Queue... 100 200 300 400 500 600 700 800 900 1000 Count of elements in the Queue = 10 Count of elements in the Queue [Updated] = 0

queue.Enqueue(300);
Console.WriteLine("Queue...");
foreach(int i in queue) {
Console.WriteLine(i);
}
Console.WriteLine("Count of elements in the Queue = "+queue.Count);
queue.Enqueue(800);
queue.Enqueue(900);
queue.Enqueue(1000);
Console.WriteLine("Count of elements in the Queue [Updated] = "+queue.Count);
queue.Clear();
Console.WriteLine("Count of elements in the Queue [Updated] = "+queue.Count);
}
}输出结果
这将产生以下输出-
Queue... 100 200 300 Count of elements in the Queue = 3 Count of elements in the Queue [Updated] = 6 Count of elements in the Queue [Updated] = 0
