突发奇想写个山寨C# Winform的消息处理器

废话不多说，先上配置文档

<?xml version="1.0" encoding="utf-8" ?><events>  <event name="BTN1" class="DAO.DAOAction" method="BtnAction"/></events>

然后是XML解析类

    class XMLContext    {        private Dictionary<string,string> sondic;        private Dictionary<string, Dictionary<string, string>> dic;        private string path;

        public Dictionary<string, string> Sondic        {            get            {                return sondic;            }        }        public Dictionary<string, Dictionary<string, string>> Dic        {            get            {                return dic;            }        }

        public XMLContext(string path)        {            this.path = path;            dic = new Dictionary<string,Dictionary<string,string>>();            sondic = new Dictionary<string,string>();        }

        public bool XML2Dictionary()        {            XmlDocument xd = new XmlDocument();            xd.Load(path);            XmlNodeList xnl = xd.SelectNodes("/events/event");            if (xnl.Count.Equals(0))            {                throw new Exception("文档出错");            }            foreach (XmlNode xn in xnl)            {                sondic["class"] = xn.Attributes["class"].Value;                sondic["method"] = xn.Attributes["method"].Value;                dic[xn.Attributes["name"].Value] = sondic;            }            return true;        }    }

继续前端控制器和应用控制器的接口

    interface IController    {        void Init();    }    interface IFrontController : IController    {        void FormAction(object sender, EventArgs e);    }    interface IApplicationController : IController    {        void FormAction(object sender, EventArgs e, Dictionary<string, string> dic);    }

前端控制器的实现：

   class FrontController : IFrontController    {        private static FrontController fc = null;        private Dictionary<string, Dictionary<string, string>> dic = null;        private IApplicationController ia = null;

        public static IFrontController Instance()        {            if (fc == null)                fc = new FrontController();            return fc;        }

        private FrontController ()        {            Init();            ia = new ApplicationController();        }

        public void FormAction(object sender, EventArgs e)        {            Control control = sender as Control;            ia.FormAction(sender, e, dic[control.Name]);        }        public void Init()        {            XMLContext xml = new XMLContext("Action.xml");            xml.XML2Dictionary();            dic = xml.Dic;        }    }

应用控制器的实现

    class ApplicationController : IApplicationController    {        public ApplicationController()        {            Init();        }        public void FormAction(object sender, EventArgs e, Dictionary<string,string> dic)        {            Process(dic["class"], dic["method"], sender, e);        }        private void Process(string className, string methodName, object sender, EventArgs e)        {            Type type = Type.GetType(className);            type.InvokeMember(methodName, BindingFlags.InvokeMethod | BindingFlags.Public | BindingFlags.Instance,               null, Activator.CreateInstance(type), new object[] { sender, e });        }        public void Init()        {        }    }

使用方式：From类写个 private void xxx(object sender, EventArgs e){

                                FrontController.Instance.FormAction(sender, e);

}

消息到这个东西，然后再配置文档里面写你要相应的名字空间，类和方法。

这个东西比较垃圾，代码侵略性大不说还没异常处理，毕竟接触C#只有一个礼拜。实习，没项目做就写写玩的。
