我怎样才能使用linq 3表

我怎样才能

linq

3个表格，在那里我可以将学生链接到学校。表格为：

学生、毕业、学校。

studentId（pk）、departId（fk）departId（pk）、schoolId（fk）schoolId（pk）

下面是两个表的链接

@foreach (var student in Model.students.Where(s => s.schoolId == item.schoolId))

你到底想要什么？你可以加入他们

var query = (from depart in Model.Depart
             join school in Model.School on depart.departId equals school.departId
             join student in Model.students on school.schoolId equals student.schoolId
             where students.schoolId == item.schoolId
             select new
             {
                 depart,
                 school,
                 student
             });

或者…

如果正确配置了关联CD，而不是联接，则还可以使用关联：

var query = from school in Model.Schools
            from dept in school.Departments
            from student in dept.Students
            select new { student, dept, school};

请添加型号和控制器。
