反射创建对象，创建泛型集合，创建泛型字典

 

 

 

           object obj = new object();

            //反射创建普通对象
             object o = Activator.CreateInstance(obj.GetType());

            //反射创建泛型集合
             Type generic = typeof(List<>);
            Type[] typeArgs1 = { obj.GetType() };
            generic=generic.MakeGenericType(typeArgs1);
            var list=Activator.CreateInstance (generic) as IList;
            
            //反射创建泛型字典
             generic = typeof(Dictionary<,>);
            Type[] typeArgs2 = { typeof(string), obj.GetType() };
            generic = generic.MakeGenericType(typeArgs2);
            var dic = Activator.CreateInstance(generic) as IDictionary;
