Javascript fullcalendar Datetime ist verkorkste

Question

ich dieses Tutorial folgenden bin ein Kalender-Scheduler in asp.net MVC5 auf machen: http://www.dotnetawesome.com/2017/07/curd-operation-on-fullcalendar-in-aspnet-mvc.html

Ich habe Probleme zu verstehen, wie die Datetime übergeben wird und warum es zeigt den Minimalwert in die Datenbank (als wäre der Wert null, weil sie leer gelassen wurde): speziell ist sie in der Datenbank auf 1/1/0001 12:00:00 AM eingestellt.

Ich habe verschiedene Antworten auf Stack Overflow untersucht, weiß aber nicht, wie oder was ich ändern muss, damit die Datetime auf einen Nicht-Null-Wert gesetzt wird.

Jede Hilfe sehr geschätzt. Hier

ist das Javascript in meiner Indexansicht

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

       events = []; 
       $.ajax({ 
        type: "GET", 
        url: "/home/GetEvents", 
        success: function (data) { 
         $.each(data, function (i, v) { 
          events.push({ 
           eventID: v.EventID, 
           title: v.Subject, 
           description: v.Description,

      function SaveEvent(data) { 
       $.ajax({ 
        type: "POST",

        data: data, 
        success: function (data) { 
         if (data.status) { 
          //Refresh the calender 
          FetchEventAndRenderCalendar();

         } 
        }, 
        error: function() { 
         alert('Failed'); 
        } 
       }) 
      } 
     }) 
    </script> 
} 

Und hier mein Controller ist:

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 } }; 
     } 
    } 
} 

Dies ist, was die Ereignisklasse wie folgt aussieht:

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

Format von Das Datum ist nicht gültig für C# automatisierte Bindung.

'DD/MM/YYYY HH:mm A' 

ändern es zu

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