How to save List value to a database in ActionResult?

Question

Hi Team

 

I am struggling to save List<SelectedIte> eNtsaDashboard = new List<SelectedItem>(); to db. Anyone can help me below logic?

  public ActionResult SaveCourse(RegCoursesViewModel regCoursesView)
      {
          try
          {
              List<SelectListItem> eNtsaDashboard = new List<SelectListItem>();
              var courseName = regCoursesView.Dashboard.CourseName;
              var courseLicence = regCoursesView.eCourses.CourseLicence;
              cb.Courses.Add(regCoursesView.Courses);
              cb.SaveChanges();
          }
          catch (Exception ex)
          {
              var error = ex.Message.ToString();
          }
          return RedirectToAction("AllCourses");
      }
// eNtsaRegCourses.
  public class RegCoursesViewModel
  {
      public eNtsaCourses Courses { get; set; }
      public eNtsaCourseList eCourses { get; set; }
      public eNtsaDashboardViewModel Dashboard { get; set; }
      public IEnumerable<SelectListItem> eNtsaDashboard { get; set; }
      public RegCoursesViewModel MainModel { get; set; }

  }
