어떻게 형태로

Question

클래스 학생에게 DataGridView에 또 다른 클래스에서

class StudentInfo 
    { 
     public int StudentId { get; set; } 
     public String FullName { get; set; } 
     public String LessonStudy { get; set; } 
     public String GroupName { get; set; } 
     public StatusStudentBell StatusStudentBell { get; set; } 
    } 

클래스 StatusStudentBell

class StatusStudentBell 
    { 
     public String Bell1 { get; set; } 
     public String Bell2 { get; set; } 
     public String Bell3 { get; set; } 
     public String Bell4 { get; set; } 
    } 

을 클래스 목록을 연결하는

ConservatoryEntities ConservatoryEntities = new ConservatoryEntities(); 
     private void Form1_Load(object sender, EventArgs e) 
     { 
      var student = ConservatoryEntities.LocationTimeClasses.Where(l => 
        l.Day.Name.Equals("Friday")); 

      var dateNow = DateTime.Parse(DateTime.UtcNow.ToShortDateString()); 

      var studentInfo = new List<StudentInfo>(); 
      foreach (var item in student) 
      { 

       studentInfo.AddRange(item.LessonToFieldStudy.FieldOfStudy.Students.ToList().Select(s => 
       new StudentInfo() 
       { 
        FullName = s.Name, 
        GroupName = s.Team.Name, 
        LessonStudy = s.FieldOfStudy.Name, 
        StatusStudentBell = new StatusStudentBell() 
        { 
         Bell1 = item.LessonToFieldStudy.RollCalls.FirstOrDefault(r => r.fk_bell_Id == 1 && 
         r.Date == dateNow)?.Absent + "", 
         Bell2 = item.LessonToFieldStudy.RollCalls.FirstOrDefault(r => r.fk_bell_Id == 2 && 
         r.Date == dateNow)?.Absent + "", 
        } 
       }).ToList()); 


      } 

     } 

저는 C#을 사용하고 있으며 초보자입니다.

C#에서는 내가 만든이 목록을 dataGridView에 연결하려고합니다.

StatusStudentBell 클래스가 DataGridView에 연결할 수있는 StudentInfo 목록을 어떻게 추가 할 수 있습니까?

도와주세요.
