发布时未保存 ASP.NET MVC 日期

Question

表单上的某些日期存在问题，无法回发。我在字段中输入了一个日期，但该应用程序似乎返回了一个空白的 DateTime -“01/01/0001 00:00:00”

这是表格：

这是发布的内容：

这是控制器：

    public ActionResult Add()
    {
        var skillsetIDs = db.SkillSets.Select(x => x.IDSkillset).Distinct();
        List<SelectListItem> items = new List<SelectListItem>();
        foreach (var t in skillsetIDs)
        {
            SelectListItem s = new SelectListItem();
            int catID = db.SkillSets.Where(c => c.IDSkillset == t).Select(x => x.IDCategory).Single();
            string product = db.SkillSets.Where(c => c.IDSkillset == t).Select(x => x.Product + " V. " + x.P_Version).Single();
            string category = db.Categories.Where(c => c.IDCategory == catID).Select(x => x.Category + ": " + x.C_Role + " - ").Single();
            s.Text = category + product;
            s.Value = t.ToString();
            items.Add(s);
        }
        ViewBag.Campaign = items;

        var personIDs = db.Personnel.Select(x => x.IDPerson).Distinct();
        List<SelectListItem> items2 = new List<SelectListItem>();
        foreach (var t in personIDs)
        {
            SelectListItem s = new SelectListItem();
            s.Text = db.Personnel.Where(c => c.IDPerson == t).Select(x => x.Fornames + " " + x.Surname).Single();
            s.Value = t.ToString();
            items2.Add(s);
        }
        ViewBag.Person = items2;
        return View();
    }

    [HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult Add(Models.PersonSkillsModel model)
    {
        try
        {
            if (ModelState.IsValid)
            {
                db.PersonSkills.Add(model);
                db.SaveChanges();
                return RedirectToAction("Index");
            }
            return RedirectToAction("Index");
        }
        catch
        {
            return View();
        }
    }

观点：

@using (Html.BeginForm()) 
{
    @Html.AntiForgeryToken()

    <div class="form-horizontal">

    </div>
}

型号：

[Table("PersonSkills")]
public class PersonSkillsModel
{
    [Key]
    public int PersonSkillsID { get; set; }

    public int IDPerson { get; set; }

    public int IDSkillSet { get; set; }

    public int Score { get; set; }

    public DateTime ScoreDate { get; set; }

    public int TargetScore { get; set; }

    public DateTime TargetDate { get; set; }

    public DateTime RefresherDate { get; set; }
}

Answer 1

能否添加数据注释并再次调试？

[DataType(DataType.Date)]
public DateTime ScoreDate { get; set; }

Answer 2

几天前我遇到了类似的问题..看看下面的一个是否有效..

使用以下属性装饰日期时间属性

[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:yyyy-MMMMM-dd}")]
