Question

用於插入數據

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(); 

我以這種方式找到了答案。這對我成功了。非常感謝您的幫助夥伴

Answer 2

數據嘗試使用此方法添加學生：

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

添加學校：

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

我希望這會有所幫助。
