dynamic关键字是编译器不检查类型

using Ruanmou.DB.Interface;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace Ruanmou.DB.MySql
{
    public class MySqlHelper : IDBHelper
    {
        public MySqlHelper()
        {
            Console.WriteLine("{0}被构造", this.GetType().Name);
        }


        public void Query()
        {
            Console.WriteLine("{0}.Query", this.GetType().Name);
        }
    }
}

Assembly assembly = Assembly.Load("Ruanmou.DB.MySql");//1 动态加载
Type type = assembly.GetType("Ruanmou.DB.MySql.MySqlHelper");//2 获取类型 完整类型名称
dynamic dDBHelper= Activator.CreateInstance(type);
dDBHelper.Query();//dynamic编译器不检查，，运行时才检查
