如何在linq中获取最后一个插入ID

Question

我有两个 table，user 和 student。 user 是 parent table 而 student 是 child table

所以来自下面的代码

public void adduserStudenttype(StudentAddUserModel s)
        {
            using (DASEntities db = new DASEntities())
            {
                user u = new user();
                u.usersEmail = s.Email;
                u.usersPassword = s.Password;
                u.usersFname = s.Fname;
                u.usersUtype = s.UserType;
                db.user.Add(u);
                db.SaveChanges();

                student stud = new student();
                stud.studentID = \ how to get the id in the user last insert??


            }     
        }

如何从 user table 中获取最后插入的内容 id？ id 是 user table 中的主键。

Answer 1

您可以通过以下方式获取：

// I suppose that the corresponding's property name is ID.
// If it is not, you should change it correspondingly.
stud.studentID = u.ID;
