将 JavaScript 日期发送到 asp.net 服务器

我想通过ajax将一个对象发送到 asp.net 服务器。对象中有更多无法识别的日期时间属性。我的意思是参数中的日期时间是默认值 => 0001.01.01

  var a = {start: new Date(), title: "asdf", description: "asdfasdf", allDay: true, end: new Date()};
$.ajax({
            url : m_serverName + "/api/calendar",
            type : "post",
            data : a,
            dataType: 'json',
            success : function() {
                console.log("ok")
            },
            error : function(request, status, error) {
                console.log(request)
            },
            xhrFields : {
                withCredentials : true
            }
        });  

只有一种方法，它是如何工作的。如果我使用 toJSON 并将其作为 JS 发送到服务器。

服务器代码：

 public HttpResponseMessage Post(CalendarEvent calendarEvent)
        {
            int id = -1;
            var httpCookie = HttpContext.Current.Request.Cookies["token"];
            if (httpCookie != null)
                if (!int.TryParse(httpCookie.Value, out id))
                    return Request.CreateResponse(HttpStatusCode.OK, false);
                else
                {
                    int employeeId = service.GetByEmployeeDevice(id).Id;
                    return Request.CreateResponse(HttpStatusCode.OK,
                                                  service.GetEventsById(employeeId));
                }
            return Request.CreateResponse(HttpStatusCode.OK, false);
        }

域模型

 [JsonObject]
    public class CalendarEvent
    {
        [JsonProperty("id")]
        public int Id { get; set; }
        [JsonProperty("employeeId")]
        public int EmployeeId { get; set; }
        [JsonProperty("title")]
        public string Title { get; set; }
        [JsonProperty("description")]
        public string Description { get; set; }
        [JsonProperty("location")]
        public string Location { get; set; }
        [JsonProperty("partner")]
        public string Partner { get; set; }
        [JsonProperty(PropertyName = "allDay")]
        public bool AllDay { get; set; }
        [JsonProperty(PropertyName = "start")]
        public DateTime Start { get; set; }
        [JsonProperty(PropertyName = "end")]
        public DateTime End { get; set; }
        [JsonProperty(PropertyName = "type")]
        public int Type { get; set; }
        [JsonIgnore]
        public Employee Employee { get; set; }
        //navigation property
        //public ICollection<AgentDevice> Devices { get; set; }
    }

我怎么能通过 ajax 发送它，没有任何转换，因为如果我有一个包含这么多对象的数组，那就非常困难了。
