反射创建BLL层控制器

 一 、配置项 

   <add key="DalPath" value="Company.Project.BLL" /> 

    <add key="DalValue" value="ControllerManager" />

二、反射创建BLL管理控制器

 public static ControllerManager Instance()        

{            

　　if (bllManager == null)            

　　{                

　　　　 string path = ConfigurationManager.AppSettings["DalPath"];

            string value = ConfigurationManager.AppSettings["DalValue"];

            Type type = Assembly.Load(path).GetType(path + "." +value);                

            ConstructorInfo ci = type.GetConstructor(System.Type.EmptyTypes);

            bllManager = (ControllerManager)ci.Invoke(null);

      }

      return bllManager;

}

三、BLL层管理控制器

    public class ControllerManager

    {        

             public ABLL aBLL

            {

                get            

                {

                      return new ABLL();            

                 }

            }        

           public BBLL bBLL

           {  

           　　get

           　　 {      

　　　　           return new BBLL();

            　　}

        　}

    }
