如下的代码是关于C# 内置队列类Queue使用范例的代码，应该是对各朋友也有好处。
using System;
using System.Collections.Generic;
class Example
{
public static void Main()
{
Queue<string> numbers = new Queue<string>();
numbers.Enqueue("one");
numbers.Enqueue("two");
numbers.Enqueue("three");
numbers.Enqueue("four");
numbers.Enqueue("five");
foreach( string number in numbers )
{
Console.WriteLine(number);
}
Console.WriteLine("nDequeuing '{0}'", numbers.Dequeue());
Console.WriteLine("Peek at next item to dequeue: {0}",
numbers.Peek());
Console.WriteLine("Dequeuing '{0}'", numbers.Dequeue());
Queue<string> queueCopy = new Queue<string>(numbers.ToArray());
Console.WriteLine("nContents of the first copy:");
foreach( string number in queueCopy )
{
Console.WriteLine(number);
}
numbers.CopyTo(array2, numbers.Count);
Queue<string> queueCopy2 = new Queue<string>(array2);
Console.WriteLine("nContents of the second copy, with duplicates and nulls:");
foreach( string number in queueCopy2 )
{
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);
}
}
one
two
three
four
five
Dequeuing 'one'
Peek at next item to dequeue: two
Dequeuing 'two'
Contents of the copy:
three
four
five
Contents of the second copy, with duplicates and nulls:
three
four
five
queueCopy.Contains("four") = True
queueCopy.Clear()
queueCopy.Count = 0
