从jQuery发送到控制器的对象列表始终为null

Question

这是我的模型课程：[Table("Question", Schema = "trs")]public class Question{    [Key]    public int QuestionId { get; set; }    [ForeignKey("TranType")]    [Required]    public int TranTypeId { get; set; }    [ForeignKey("Company")]    [Required]    public int CompanyId { get; set; }    [Required]    [StringLength(300)]    public string Text { get; set; }    [Required]    public bool IsActive { get; set; }    [ForeignKey("QuestionType")]    public int QTypeId { get; set; }    public DateTime CreatedDate { get; set; }    public string CreatedUserId { get; set; }    public DateTime UpdateDate { get; set; }    public string UpdateUserId { get; set; }    public Company Company { get; set; }    public QuestionType QuestionType { get; set; }    public TranType TranType { get; set; }    public ICollection<Answer> Answer { get; set; }    public ICollection<Grading> Grading { get; set; }}这是我的控制器操作，现在它什么也不做，因为我需要首先获取出现问题的值：[Authorize(Roles = "Admin")]public class QuestionController : Controller{    readonly IQuestionRepository questionRepository;    readonly ICompanyRepository companyRepository;    public QuestionController(IQuestionRepository qRepository, ICompanyRepository cpnRepository)    {        questionRepository = qRepository;        companyRepository = cpnRepository;    }     [HttpPost]    public ActionResult Save([FromBody] List<Question> qView)    {        return View(qView);    }}现在我也尝试过： [HttpPost] public ActionResult Save(List<Question> qView) {        return View(qView); }在这两种情况下，我都有问题；在第一个选项中（带有[FromBody]），qView为null；在选项2中（没有[FromBody]），qView不为null，但List为空（Count == 0）。请问我的问题在哪里？
