C#中的Queue.Synchronized()方法
C#中的Queue.Synchronized()方法用于返回包装原始队列并且是线程安全的新Queue。
语法
语法如下-
public static System.Collections.Queue Synchronized (System.Collections.Queue queue);
在上方，参数队列是要同步的队列。
示例
现在让我们看一个例子-
using System;
using System.Collections;
public class Demo {
public static void Main(){
Queue queue = new Queue();
queue.Enqueue("AB");
queue.Enqueue("BC");
queue.Enqueue("CD");
queue.Enqueue("DE");
queue.Enqueue("EF");
queue.Enqueue("FG");
queue.Enqueue("GH");
queue.Enqueue("HI");
Console.WriteLine("Queue...");
IEnumerator demoEnum = queue.GetEnumerator();
while (demoEnum.MoveNext()){
Console.WriteLine(demoEnum.Current);
}
Console.WriteLine("Is Queue synchronized? = "+queue.IsSynchronized);
Queue queue2 = Queue.Synchronized(queue);
Console.WriteLine("Is Queue synchronized now? = "+queue2.IsSynchronized);
}
}输出结果
这将产生以下输出-
Queue... AB BC CD DE EF FG GH HI Is Queue synchronized? = False Is Queue synchronized now? = True
示例
现在让我们来看另一个示例-
using System;
using System.Collections;
public class Demo {
public static void Main(){
Queue queue = new Queue();
queue.Enqueue(100);
queue.Enqueue(200);
queue.Enqueue(300);
Console.WriteLine("Is Queue synchronized? = "+queue.IsSynchronized);
Queue queue2 = Queue.Synchronized(queue);
Console.WriteLine("Is Queue synchronized now? = "+queue2.IsSynchronized);
Console.Write("Count of elements = ");
Console.WriteLine(queue.Count);
Console.WriteLine("Queue...");
foreach(int i in queue){
Console.WriteLine(i);
}
Console.WriteLine("Does the queue has element 500? = "+queue.Contains(500));
int[] intArr = new int[5];
intArr[0] = 1;
intArr[1] = 2;
intArr[2] = 3;
intArr[3] = 4;
queue.CopyTo(intArr, 1);
Console.WriteLine("\nQueue (Updated)");
foreach(int i in queue){
Console.WriteLine(i);
}
Console.WriteLine("\nArray (Updated)");
foreach(int i in intArr){
Console.WriteLine(i);
}
}
}输出结果
这将产生以下输出-
Is Queue synchronized? = False Is Queue synchronized now? = True Count of elements = 3 Queue... 100 200 300 Does the queue has element 500? = False Queue (Updated) 100 200 300 Array (Updated) 1 100 200 300 0
