本文介绍了一种使用原型模式实现颜色管理的方法。通过定义颜色基类并实现Clone方法，可以轻松复制颜色实例。ColorManager类利用字典存储各种预定义及用户自定义的颜色，支持颜色的克隆与检索。

using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace Prototype { class Program { static void Main(string[] args) { ColorManager colormanager = new ColorManager(); // Initialize with standard colors colormanager["red"] = new Color(255, 0, 0); colormanager["green"] = new Color(0, 255, 0); colormanager["blue"] = new Color(0, 0, 255); // User adds personalized colors colormanager["angry"] = new Color(255, 54, 0); colormanager["peace"] = new Color(128, 211, 128); colormanager["flame"] = new Color(211, 34, 20); // User clones selected colors Color color1 = colormanager["red"].Clone() as Color; Color color2 = colormanager["peace"].Clone() as Color; Color color3 = colormanager["flame"].Clone() as Color; // Wait for user Console.ReadKey(); } } /// <summary> /// The 'Prototype' abstract class /// </summary> abstract class ColorPrototype { public abstract ColorPrototype Clone(); } /// <summary> /// The 'ConcretePrototype' class /// </summary> class Color : ColorPrototype { private int _red; private int _green; private int _blue; // Constructor public Color(int red, int green, int blue) { this._red = red; this._green = green; this._blue = blue; } // Create a shallow copy public override ColorPrototype Clone() { Console.WriteLine( "Cloning color RGB: {0,3},{1,3},{2,3}", _red, _green, _blue); return this.MemberwiseClone() as ColorPrototype; } } /// <summary> /// Prototype manager /// </summary> class ColorManager { private Dictionary<string, ColorPrototype> _colors = new Dictionary<string, ColorPrototype>(); // Indexer public ColorPrototype this[string key] { get { return _colors[key]; } set { _colors.Add(key, value); } } } }
