C#内置队列类Queue用法实例
本文实例讲述了C#内置队列类Queue用法。分享给大家供大家参考。具体分析如下：
这里详细演示了C#内置的队列如何进行添加，移除等功能。
usingSystem;
usingSystem.Collections.Generic;
classExample
{
publicstaticvoidMain()
{
Queue<string>numbers=newQueue<string>();
numbers.Enqueue("one");
numbers.Enqueue("two");
numbers.Enqueue("three");
numbers.Enqueue("four");
numbers.Enqueue("five");
//Aqueuecanbeenumeratedwithoutdisturbingitscontents.
foreach(stringnumberinnumbers)
{
Console.WriteLine(number);
}
Console.WriteLine("\nDequeuing'{0}'",numbers.Dequeue());
Console.WriteLine("Peekatnextitemtodequeue:{0}",
numbers.Peek());
Console.WriteLine("Dequeuing'{0}'",numbers.Dequeue());
//Createacopyofthequeue,usingtheToArraymethodandthe
//constructorthatacceptsanIEnumerable<T>.
Queue<string>queueCopy=newQueue<string>(numbers.ToArray());
Console.WriteLine("\nContentsofthefirstcopy:");
foreach(stringnumberinqueueCopy)
{
Console.WriteLine(number);
}
//Createanarraytwicethesizeofthequeueandcopythe
//elementsofthequeue,startingatthemiddleofthe
//array.
string[]array2=newstring[numbers.Count*2];
numbers.CopyTo(array2,numbers.Count);
//Createasecondqueue,usingtheconstructorthatacceptsan
//IEnumerable(OfT).
Queue<string>queueCopy2=newQueue<string>(array2);
Console.WriteLine("\nContentsofthesecondcopy,withduplicatesandnulls:");
foreach(stringnumberinqueueCopy2)
{
Console.WriteLine(number);
}
Console.WriteLine("\nqueueCopy.Contains(\"four\")={0}",
queueCopy.Contains("four"));
Console.WriteLine("\nqueueCopy.Clear()");
queueCopy.Clear();
Console.WriteLine("\nqueueCopy.Count={0}",queueCopy.Count);
}
}
/*Thiscodeexampleproducesthefollowingoutput:
