解析错误的日期格式

Question

我使用bootstraps datepicker来选择日期，并使用下拉列表来选择供应商。选择供应商时，应向我显示供应商的拒绝原因。但问题是，我没有得到dd-mm-yyyy那天，而是在控制器的GetRejectedCauses中得到mm-dd-yyyy。脚本中的startTime和endTime向我显示正确的格式dd-mm-yyyy。因此，在将日期格式解析为控制器时，某些事情会出错！

<div class="form-group">

模型

   [Display(Name = "Date From")]
   [DataType(DataType.Date)]
   [DisplayFormat(DataFormatString = "{0:yyyy-MM-dd}",  
    ApplyFormatInEditMode = true)]
    public DateTime ?StartTime { get; set; }

    [Display(Name = "Date To")]
    [DataType(DataType.Date)]
    public DateTime? EndTime { get; set; }

控制器

    public JsonResult GetRejectedCauses(Rejected model)
    {
        return Json
            (
            new { success = true,
                SelectedSupplier = model.SelectedSupplier                 
            }, JsonRequestBehavior.AllowGet);
    }
