如何通过ViewModel在EF内核中使用.Include()

public class Student
{
    public int Id { get; set; }
    public string Name { get; set; }
    public List<Course> Courses { get; set; }
}

public class Course
{
    public int Id { get; set; }
    public string Title { get; set; }
    public int StudentId { get; set; }
    public Student Student { get; set; }
}

public class StudentCourseViewModel
{
    public int StudentId { get; set; }
    public string StudentName { get; set; }
    public List<Course> Courses { get; set; }
}

public class StudentController : Controller
{
    private readonly ApplicationDbContext _context;

    public StudentController(ApplicationDbContext context)
    {
        _context = context;
    }

    public async Task<IActionResult> Details(int? id)
    {
        if (id == null)
        {
            return NotFound();
        }

        var student = await _context.Students
            .Include(s => s.Courses)
            .FirstOrDefaultAsync(m => m.Id == id);

        if (student == null)
        {
            return NotFound();
        }

        var viewModel = new StudentCourseViewModel
        {
            StudentId = student.Id,
            StudentName = student.Name,
            Courses = student.Courses
        };

        return View(viewModel);
    }
}

var students = await _context.Students
    .Include(s => s.Courses)
    .ToListAsync();

var viewModel = _context.Students
    .Where(s => s.Id == id)
    .Select(s => new StudentCourseViewModel
    {
        StudentId = s.Id,
        StudentName = s.Name,
        Courses = s.Courses
    })
    .FirstOrDefault();
