自定义动态对象

1，自定义动态对象需要继承DynamicObject类

2，可根据需要，重写不同的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>
        /// 为获取成员值的操作提供实现
        /// </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>
        /// 为设置成员值的操作提供实现
        /// </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;
        }
    }
}

-----------------------------------------------------主程序

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")); //输出：b|b
            Console.ReadKey();
        }
    }
