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。
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"); // A queue can be enumerated without disturbing its contents. 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()); // Create a copy of the queue, using the ToArray method and the // constructor that accepts an IEnumerable<T>. Queue<string> queueCopy = new Queue<string>(numbers.ToArray()); Console.WriteLine("nContents of the first copy:"); foreach( string number in queueCopy ) { Console.WriteLine(number); } // Create an array twice the size of the queue and copy the // elements of the queue, starting at the middle of the // array. string[] array2 = new string[numbers.Count * 2]; numbers.CopyTo(array2, numbers.Count); // Create a second queue, using the constructor that accepts an // IEnumerable(Of T). 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); } } /* This code example produces the following output: 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 */
希望本文所述对大家的C#程序设计有所帮助。
