MVC 中的日期时间参数

Question

我正在编写一个程序，我将 DateTime 变量发送到 sortable jQuery DataTable。这是我的 "Model" 文件中的构造函数：

 public StudentDailyStatus(int studentID, DateTime startDate, DateTime endDate, string code, string status, int goodDays, int badDays, int leave, int lengthOfStay)

然后是我试图放入对象的值：

 new StudentDailyStatus(1, (2015, 1, 1), (2015, 2, 1), "1","Normal","2",0,0,0),

我的错误是：“[文件] 不包含采用 4 个参数的构造函数”。

但是 startDate 和 endDate 参数有问题。如何使用 DateTime 变量？感谢您的帮助！

填充 table 的文件是：

@{
    ViewBag.Title = "Student - Daily Status";
    ViewBag.SubTitle = "Status History";
}

@Html.Partial("_StudentNavPartial")
@Html.Partial("_StudentSearchBar")
<div class="container-fluid left">
    <h4>@ViewBag.SubTitle</h4>

    <div class="container-fluid left">

好的，这是控制器：

using System;
using System.Collections;
using System.Collections.Generic;
using System.Data;
using System.Data.Entity;
using System.Linq;
using System.Net;
using System.Web;
using System.Web.Mvc;
using SAAS.Models;
using SAAS.Services;

namespace SAAS.Controllers
{
    public class StudentDailyStatusController : Controller
    {

        // GET: StudentDailyStatus
        public ActionResult DailyStatus()
        {
            return View();
        }
        public JsonResult GetData(DTParameters dtModel, FilterViewModel filterModel)
        {
            try
            {
                List<StudentDailyStatus> data = new StudentDailyStatusService().GetStudentDailyStatuses(dtModel.Start, dtModel.Length);
                int count = new StudentDailyStatusService().Count();
                DTResult<StudentDailyStatus> result = new DTResult<StudentDailyStatus>
                {
                    draw = dtModel.Draw,
                    data = data,
                    recordsFiltered = count,
                    recordsTotal = count
                };
                return Json(result);
            }
            catch (Exception ex)
            {
                return Json(new { error = ex.Message });
            }
        }

    }
}

这里是 "models" 文件：

using System;
using System.ComponentModel.DataAnnotations;
using System.Data.Entity;

namespace SAAS.Models
{
    public class StudentDailyStatus

Answer 1

您只是发送 ("2015,01,...") 而不是日期。您必须先创建一个 dateTime 对象，然后发送给您的构造函数。

new Date(year, month, day, hours, minutes, seconds, milliseconds);

进一步参考检查http://www.w3schools.com/jsref/jsref_obj_date.asp

Answer 2

(2015, 1, 1) 不是 DateTime 值...请改用 new DateTime(2015, 1, 1)

Answer 3

好的，如果您输入的日期是这样的，(2015, 2, 1) 那么您就错了。

您需要像这样将日期作为参数传递...new DateTime(2015, 2, 1)

所以，这应该是您的构造函数调用...

new StudentDailyStatus(1, new DateTime(2015, 1, 1), new DateTime(2015, 2, 1), "1","Normal","2",0,0,0)
