linq - Custom Collection extends List Add method

Question

I want to create a custom collection and add my own custom Add method. Scenario:

Teacher.Students.Add(Student s)

I want to put LINQ methods to save the teacher/student relationship to the database, not just add it to the list.

How can I do that? How can I know what "Teacher" object this is?

Answer 1

您最好的选择是设置和配置一个 ORM（对象关系映射），例如NHibernate，它将为您管理这个。实际上，您设置了数据模型，ORM 框架将负责为您保存该信息。
