MVC 中的日期时间参数

Question

我正在开发一个程序，我将一个DateTime 变量发送到一个可排序的jQuery DataTable。 这是我的“模型”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)

然后这里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] 不包含接受 4 个参数的构造函数”。

但我遇到了startDate 和endDate 参数的问题。如何使用DateTime 变量？ 感谢您的帮助！

            StudentDailyStatuses = new List<StudentDailyStatus>
            {
                // StudentID, StartDate, EndDate, Code, Status, GoodDays, BadDays, Leave, LengthOfStay
                new StudentDailyStatus(1, new DateTime(2015, 1, 1), new DateTime(2015, 2, 1), "1","Normal",2,0,0,0),

填充表格的文件是：

}

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 });
            }
        }

    }
}

这是“模型”文件：

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

namespace SAAS.Models
{

Answer 1

好的，如果您要输入这样的日期，(2015, 2, 1)，那您就错了。

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

所以，这应该是你的构造函数调用...

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

Answer 2

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);

Answer 3

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