自訂動態對象

標籤：public   動態   dynamicobject   

1，自訂動態對象需要繼承DynamicObject類

2，可根據需要，重寫不同的DynamicObject方法

-----------------------------------------------------DynamicClass.cs

 using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;using System.Dynamic;namespace ConsoleApplication3{    public class DynamicClass:DynamicObject    {        Dictionary<string, object> _dynamicData = new Dictionary<string, object>();        /// <summary>        /// 為擷取成員值的操作提供實現        /// </summary>        /// <param name="binder"></param>        /// <param name="result"></param>        /// <returns></returns>        public override bool TryGetMember(GetMemberBinder binder, out object result)        {            bool success = false;            result = null;            if (_dynamicData.ContainsKey(binder.Name))            {                result = _dynamicData[binder.Name];                success = true;            }            else            {                result = "Property Not Found";                success = false;            }            return success;        }        /// <summary>        /// 為設定成員值的操作提供實現        /// </summary>        /// <param name="binder"></param>        /// <param name="value"></param>        /// <returns></returns>        public override bool TrySetMember(SetMemberBinder binder, object value)        {            _dynamicData[binder.Name]= value;            return true;        }    }}

-----------------------------------------------------主程式

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;using System.Dynamic;namespace ConsoleApplication3{    class Program    {        static void Main(string[] args)        {            dynamic dyn = new DynamicClass();            dyn.name = "a";            dyn.aa = new Func<string,string>(r => r);            dyn.name = "b";            Console.WriteLine(dyn.name+"|"+ dyn.aa("b")); //輸出：b|b            Console.ReadKey();        }    }}
