自己动手写ORM框架(一):目标效果预览

    最终实现后达到的效果，只需写少量代码就可实现CURD操作。

DAL层代码：

public class StudentDAL
    {
        EntityManager entityManager = EntityManagerFactory.CreateEntityManager();

        public StudentDAL() { }
        public StudentDAL(IDbTransaction transaction)
        {
            entityManager.Transaction = transaction;
        }

        public List<StudentEntity> FindAll()
        {
            return entityManager.FindAll<StudentEntity>();
        }
       
        public int Save(StudentEntity entity)
        {
            return entityManager.Save(entity);
        }

        public int Update(StudentEntity entity)
        {
            return entityManager.Update(entity);
        }

        public int Remove(StudentEntity entity)
        {
            return entityManager.Remove(entity);
        }

        public int Remove(object id)
        {
            return entityManager.Remove<StudentEntity>(id);
        }              

        public  List<StudentEntity> FindById(object id)
        {
            return entityManager.FindById<StudentEntity>(id);
        }

        public  List<StudentEntity> FindByProperty(string propertyName,object value)
        {
            return entityManager.FindByProperty<StudentEntity>(propertyName, value);
        }
    }
