谁能告诉我如何插入数据

Table Student has columns {stuId Name Age}

Answer 1

                String SchooID = getNewID();
                Schools schl = new Schools();
                schl.school_reference = SchooID;
                schl.school_name = "Ananda Collage";

                schl.StudentReference.Value = cecbContext.Students.First(i => i.stud_name == "Josh");


                cecbContext.AddToSchools(schl);
                cecbContext.SaveChanges();

我以这种方式找到了答案。这对我很成功。非常感谢你们的帮助

Answer 2

试试这个来添加学生：

Student student = new Student(){studId="", Name="", Age=""};
myEntities.Students.AddObject(student);
myEntities.SaveChanges();

添加学校：

School school = new School(){classId="", Year = year, sName=""};
myEntities.Schools.AddObject(school);
myEntities.SaveChanges();

我希望这有帮助。
