在Code First Fluent API中定义关系 [英] Defining relationships in Code First Fluent API

问题描述

我刚开始使用EF Code First。我对此有疑问。通过Fluent API定义关系有什么好处？



当我从我的poco（或实体）创建数据库时，我已经有了一对多和/或我的表之间的多对多关系。



例如：

Hi,

I just started with EF Code First. And I have a question about this. What is the advantage of defining relationships through the Fluent API?

When I create the database from my poco's (or entities) I already have one-to-many and/or many-to-many relationships between my tables.

For ex:

public class School
    {
        public School()
        {
            Students = new List<Student>();
        }

        public Guid Id { get; set; }
        public string Name { get; set; }
        public List<Student> Student{ get; set; }
    }


public class Student
    {
        public Guid Id { get; set; }
        public string Firstname { get; set; }
        public string Lastname { get; set; }
        public Guid SchoolId{ get; set; }
        public School School{ get; set; }
    }

这创建了学生和学校之间的关系。通过Fluent API定义关系是否有优势？或者不是吗？



提前致谢！

This creates already a relationship between Students and School. Does defining a relationship through the Fluent API gives advantages? Or not?

Thanks in advance!
