乐在其中设计模式(C#) - 原型模式(Prototype Pattern).doc

介绍用原型实例指定创建对象的种类，并且通过拷贝这个原型来创建新的对象。示例有一个Message实体类，现在要克隆它。MessageModel
usingSystem;usingSystem.Collections.Generic;usingSystem.Text;namespacePattern.Prototype{/**////<summary>///Message实体类///</summary>publicclassMessageModel{/**////<summary>///构造函数///</summary>///<paramname="msg">Message内容</param>///<paramname="pt">Message发布时间</param>publicMessageModel(stringmsg,DateTimept){this._message=msg;this._publishTime=pt;}privatestring_message;/**////<summary>///Message内容///</summary>publicstringMessage{get{return_message;}set{_message=value;}}HYPERLINK"http://qianming.wan128.cn"http://qianming.wan128.cnprivateDateTime_publishTime;/**////<summary>///Message发布时间///</summary>publicDateTimePublishTime{get{return_publishTime;}set{_publishTime=value;}}}}
ShallowCopy
usingSystem;usingSystem.Collections.Generic;usingSystem.Text;namespacePattern.Prototype{/**////<summary>///浅拷贝///</summary>publicclassShallowCopy:ICloneable{/**////<summary>///构造函数///</summary>publicShallowCopy(){}/**////<summary>///实现ICloneable的Clone()方法///</summary>///<returns></returns>publicObjectClone(){returnthis.MemberwiseClone();}HYPERLINK"http://yin.qqlove789.com"http://yin.qqlove789.comprivateMessageModel_mm;/**////<summary>///Message实体对象///</summary>publicMessageModelMessageModel{get{return_mm;}set{_mm=value;}}}}
DeepCopy
usingSystem;usingSystem.Collections.Generic;usingSystem.Text;namespacePattern.Prototype{/**////<summary>///深拷贝///</summary>publicclassDeepCopy:ICloneable{/**////<summary>///构造函数///</summary>publicDeepCopy(){}/**////<summary>///构造函数///</summary>///<paramname="mm">Message实体对象</param>publicDeepCopy(MessageModelmm){_mm=mm;}/**////<summary>///实现ICloneable的Clone()方法///</summary>///<returns></returns>publicObjectClone(){returnnewDeepCopy(newMessageModel(_mm.Message,_mm.PublishTime));}privateMessageModel_mm;/**////<summary>///Message实体对象///</summary>publicMessageModelMessageModel{get{return_mm;}set{_mm=value;}}}}
