C#的反射明显的比AS3的反射要强很多啊。可以从外部访问到类的私有成员。举个例子:
Type _class = this.GetType(); FieldInfo _field = _class.GetField(@fieldName, BindingFlags.Instance | BindingFlags.NonPublic);
枚举 : BindingFlags.NonPublic ->非公共成员将包括在内进行搜索,意思就是private成员也可以搜索到。
在model中注册须发的主题(User)
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using BindLib.com; namespace BindDemo.com.model { public sealed class User : BaseDataModel { private int _hp = 1000; public int Hp { get { return _hp; } //绑定hp(血量) set { this.ChangeValue<int>("Hp","_hp",value); } } private bool _isLive = false; public bool IsLive { get { return _isLive; } set { this.ChangeValue<bool>("IsLive", "_isLive", value); } } } }
这的注意的是字段_hp和字段_isLive都是private(私用的): 这个和AS3绑定(见 AS3 属性绑定/上一篇)有很大的不同,这得益于C#可以从外部访问private
view中需要绑定(注册侦听)(UserView)
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using BindLib; namespace BindDemo.com.model { public sealed class UserView { public User user; private int _hp; public int Hp { set { this._hp = value ; Console.WriteLine("血量 {0}", value); } get { return this._hp; } } public UserView() { user = new User(); BindTools.BindProperty<int>(this, "Hp", user, "Hp", true); BindTools.BindSetter<bool>(this.UpdateIsLive, user, "IsLive",true); } private void UpdateIsLive(bool @isLive) { Console.WriteLine(@isLive ? "活着" : "战死"); } } }
好了 , 具体参数意思可以参考(《AS3 属性绑定》篇,上篇)
测试:
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using BindDemo.com.model; namespace BindDemo { class Program { static void Main(string[] args) { UserView _uM = new UserView(); Console.WriteLine("获得hp : {0}" , _uM.Hp); User uR = _uM.user; uR.Hp = 89; Console.WriteLine("改变获得hp : {0}", _uM.Hp); Console.WriteLine("-------------------------------------------------"); uR.IsLive = true; Console.WriteLine("#################################################"); uR.IsLive = false; Console.ReadLine(); } } }
结果:
