我通过将学生传入视图然后访问他们的问题来输出学生记录的问题:
foreach (var item in Model.Student.Problems) {
我在徘徊如何通过ProblemDateTime属性对这些项目进行排序?我注意到我放了一个。在问题之后有一个OrderByDescending选项,我不完全确定如何使用它?
任何帮助都将不胜感激。
谢谢,
乔恩

我倾向于使用由Student和Problems作为不同属性组成的不同ViewModel
public class MyViewModel
{
public Student Student { get; set; }
public IList<Problem> Problems { get; set; }
}
然后你的Controller应该负责退回学生和正确的问题
public ActionResult MyAction(int studentID)
{
var model = new MyViewModel();
//below is just an example:
//would be much better if you had a service/repository layer
//that you could call to return your information
model.Student = _db.Students.FirstOrDefault(s => d.ID == studentID);
model.Problems = _db.Problems.Where(p => p.StudentID == studentID)
.OrderByDescenging(p => p.Date)
.ToList();
return View(model);
}
