javascript fullcalendar 日期时间搞砸了

Question

我正在学习这个关于在 asp.net MVC5 中制作日历调度程序的教程: http://www.dotnetawesome.com/2017/07/curd-operation-on-fullcalendar-in-aspnet-mvc.html

我无法理解日期时间是如何传递的，以及为什么它在数据库中显示最小值(就好像该值是空的，因为留空):具体来说，它被设置为 1/1/0001 12:00: 00 AM 在数据库中。

我查看了 Stack Overflow 上的各种答案，但不知道我需要如何更改或更改什么才能将日期时间设置为非空值。

非常感谢任何帮助。

这是我的索引 View 中的 javascript

  <script>
        $(document).ready(function () {
            var events = [];
            var selectedEvent = null;
            FetchEventAndRenderCalendar();
            function FetchEventAndRenderCalendar() {

                })
            }
        })
    </script>
}

这是我的 Controller :

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;

namespace FamilyCalendar2.Controllers
{
    public class HomeController : Controller
    {
        // GET: Home
        public ActionResult Index()
        {
            return View();
        }

        public JsonResult GetEvents()
        {
            using (Entities1 dc = new Entities1())
            {
                var events = dc.Event.ToList();
                return new JsonResult { Data = events, JsonRequestBehavior = JsonRequestBehavior.AllowGet };
            }
        }

        [HttpPost]
        public JsonResult SaveEvent(Event e)
        {
            var status = false;
            using (Entities1 dc = new Entities1())
            {
                if (e.EventID > 0)
                {
                    //Update the event
                    var v = dc.Event.Where(a => a.EventID == e.EventID).FirstOrDefault();
                    if (v != null)
                    {
                        v.Subject = e.Subject;
                        v.Start = e.Start;
                        v.End = e.End;
                        v.Description = e.Description;
                        v.IsFullDay = e.IsFullDay;
                        v.ThemeColor = e.ThemeColor;
                    }
                }
                else
                {

                    dc.Event.Add(e);
                }

                dc.SaveChanges();
                status = true;

            }
            return new JsonResult { Data = new { status = status } };
        }

        [HttpPost]
        public JsonResult DeleteEvent(int eventID)
        {
            var status = false;
            using (Entities1 dc = new Entities1())
            {
                var v = dc.Event.Where(a => a.EventID == eventID).FirstOrDefault();
                if (v != null)
                {
                    dc.Event.Remove(v);
                    dc.SaveChanges();
                    status = true;
                }
            }
            return new JsonResult { Data = new { status = status } };
        }
    }
}

这是事件类的样子:

namespace FamilyCalendar2
{
    using System;
    using System.Collections.Generic;

    public partial class Event
    {
        public int EventID { get; set; }
        public string Subject { get; set; }
        public string Description { get; set; }
        public System.DateTime Start { get; set; }
        public Nullable<System.DateTime> End { get; set; }
        public string ThemeColor { get; set; }
        public Nullable<bool> IsFullDay { get; set; }
        public string User { get; set; }
    }
}

Answer 1

日期格式不适用于 C# 自动绑定(bind)。

'DD/MM/YYYY HH:mm A'

改成

'DD/MM/YYYY HH:mm:ss'
