WebSharp Aspect改进（续2）

    接着上次在《朗志轻量级项目管理解决方案》中对Aspect的改进，
注意，这里我们实现了IXmlSerialization接口，以实现自定义的反序列化操作，还应注意的是在反串行的过程中，这里我们使用了一个自已实现的深拷贝DeepCopy

public class AspectCollection:CollectionBase,IXmlSerializable
    {
        public AspectCollection()
        {
            //
            // TODO: 在此处添加构造函数逻辑
            //
        }
        public void Add(AspectItem ai)
        {
            this.InnerList.Add(ai);
        }
        public new AspectItem this[int index]
        {
            get
            {
                return this.InnerList[index] as AspectItem;
            }
            set
            {
                this.InnerList[index]=value;
            }

        }
        IXmlSerializable 成员#region IXmlSerializable 成员

        public void WriteXml(XmlWriter writer)
        {
            // TODO:  添加 AspectCollection.WriteXml 实现
            foreach(AspectItem ai in this.InnerList)
            {
                writer.WriteStartElement("Aspect");
                writer.WriteAttributeString("","type","",ai.Type);
                writer.WriteAttributeString("","deploy-model","",ai.DeployModel);
                writer.WriteAttributeString("","pointcut-type","",ai.PointCutType);
                writer.WriteAttributeString("","action-position","",ai.ActionPosition);
                ai.Rules.WriteXml(writer);
                writer.WriteEndElement();
             }
        }

        public System.Xml.Schema.XmlSchema GetSchema()
        {
            // TODO:  添加 AspectCollection.GetSchema 实现
            return null;
        }

        public void ReadXml(XmlReader reader)
        {
            // TODO:  添加 AspectCollection.ReadXml 实现
            base.Clear();
            reader.MoveToContent();
            AspectCollection ac=new AspectCollection();
            RuleCollection rc=new RuleCollection();
            AspectItem ai=new AspectItem();
            while(reader.Read())
            {
                if (reader.IsStartElement("Aspect"))
                {
                    ai=new AspectItem();
                    rc.Clear();
                    reader.MoveToAttribute("type");
                    ai.Type=reader.Value;
                    reader.MoveToAttribute("deploy-model");
                    ai.DeployModel=reader.Value;
                    reader.MoveToAttribute("pointcut-type");
                    ai.PointCutType=reader.Value;
                    reader.MoveToAttribute("action-position");
                    ai.ActionPosition=reader.Value;
                    this.Add(ai);
                    continue;
                }

                if (reader.IsStartElement("Rule"))
                {
                    RuleItem ri=new RuleItem();
                    reader.MoveToAttribute("type");
                    ri.type=reader.Value;
                    reader.MoveToAttribute("match");
                    ri.match=reader.Value;
                    rc.Add(ri);
                    ai.Rules=rc.DeepCopy();
                }

            }        
        }

这里我使用了.net内置的序列化功能

using System;
using System.Xml.Serialization;
namespace Langzhi.Aspect
{
    /**//// <summary>
    /// AspectItem 的摘要说明。
    /// </summary>
    [Serializable()]
    public class AspectItem
    {
        public AspectItem()
        {
            //
            // TODO: 在此处添加构造函数逻辑
            //
        }
        private string m_Type;
        private string m_DeployModel;
        private string m_PointCutType;
        private string m_ActionPosition;
        private RuleCollection m_RuleCollection;
//        private string m_ID;
        private string m_AssemblyName;
        private string m_ClassName;
        [XmlAttribute("type")]
        public string Type
        {
            get
            {
                return this.m_Type;
            }
            set
            {
                this.m_Type=value;
            }
        }
        [XmlAttribute("deploy-model")]
        public string DeployModel
        {
            get
            {
                return this.m_DeployModel;
            }
            set
            {
                this.m_DeployModel=value;
            }
        }
        [XmlAttribute("pointcut-type")]
        public string PointCutType
        {
            get
            {
                return this.m_PointCutType;
            }
            set
            {
                this.m_PointCutType=value;
            }
        }
        [XmlAttribute("action-position")]
        public string ActionPosition
        {
            get
            {
                return this.m_ActionPosition;
            }
            set
            {
                this.m_ActionPosition=value;
            }
        }
//        [XmlAttribute("id")]
//        public string ID
//        {
//            get
//            {
//                return this.m_ID;
//            }
//            set
//            {
//                this.m_ID = value;
//            }
//            
//        }
        [NonSerialized()]
        public string ID;
        [NonSerialized()]
        public string AssemblyName;
        [NonSerialized()]
        public string ClassName;
        [NonSerialized()]
        public IAspect SingletonAspect;
        public RuleCollection Rules
        {
            get
            {
                return this.m_RuleCollection;                
            }
            set
            border-right: #808080 1px solid;
