Multiple Models in Single View in MVC

Question

Hello, I am trying to replicated this http://www.c-sharpcorner.com/UploadFile/ff2f08/multiple-models-in-single-view-in-mvc/Default.aspx for my project but I am unable to load the data from database. 

 

In that example it gets all the faculty and students this way

private List<Teacher> GetTeachers()
{
List<Teacher> teachers = new List<Teacher>();
teachers.Add(new Teacher { TeacherId = 1, Code = "TT", Name = "Tejas Trivedi" });
teachers.Add(new Teacher { TeacherId = 2, Code = "JT", Name = "Jignesh Trivedi" });
teachers.Add(new Teacher { TeacherId = 3, Code = "RT", Name = "Rakesh Trivedi" });
return teachers;
}

 

Assuming that I also have public class Teacher / Student class How could I load the values from the database?   

 private List<Teacher> GetTeachers()
{

DBContextEntities db = new DBContextEntities();
List<Teacher> teachers = new List<Teacher>();
????
return teachers;
}
