原文:https://www . geesforgeks . org/queue-clear-method-in-c-sharp/
此方法用于从队列中移除对象。这个方法是一个 O(n)运算，其中 n 是元素的总数。这个方法属于系统。集合命名空间。
语法:
public void Clear ();
下面给出了一些例子，以便更好地理解实现:
例 1:
// C# code to illustrate the
// Queue.Clear Method
using System;
using System.Collections;
class GFG {
// Driver code
public static void Main()
{
// Creating a Queue
Queue q = new Queue();
// Inserting the elements into the Queue
q.Enqueue(1);
q.Enqueue(2);
q.Enqueue(2);
q.Enqueue(4);
// Displaying the count of elements
// contained in the Queue before
// removing all the elements
Console.Write("Total number of elements "+
"in the Queue are : ");
Console.WriteLine(q.Count);
// Removing all elements from Queue
q.Clear();
// Displaying the count of elements
// contained in the Queue after
// removing all the elements
Console.Write("Total number of elements"+
" in the Queue are : ");
Console.WriteLine(q.Count);
}
}
输出:
Total number of elements in the Queue are : 4
Total number of elements in the Queue are : 0
