如何在数据 Table 中显示时间？仅显示 Obj obj 的数据表

Question

我的数据table只显示

Here is what Data table Shows

这是我在 EmployeeSettings Controller 上的代码，用于从数据库 table 获取数据。我已经尝试将其转换为字符串或日期时间，但会出现错误 Cannot convert System.TimeSpan to String/DateTime

   public ActionResult GetData()
    {
        var employeesetting = (from es in db.EmployeeSettingss.ToList()
                              join e in db.Employees.ToList() on es.EmployeeId equals e.Id

                          select new EmployeeSettingsListModel
                          {
                              Id = es.Id,
                              EmployeeName = e.FirstName + " " + e.MiddleName + " " + e.LastName,
                              EmployeeIn = es.EmployeeIn,
                              EmployeeOut = es.EmployeeOut,
                          });

    return Json(new { data = employeesetting.ToList() }, JsonRequestBehavior.AllowGet);
}

这是我的观点，我声明了一些 ajax 供 table 加载。

@using PayrollWeb.Models
@model PayrollWeb.Models.EmployeeSettingsFormModel
@{
    ViewBag.Title = "AddOrEdit";
    Layout = "~/Views/Shared/_Layout.cshtml";
}

@using (Html.BeginForm("AddOrEdit", "EmployeeSettings", FormMethod.Post, new { onsubmit = "return SubmitFormEmployeeSettings(this)" }))
{
    @Html.HiddenFor(model => model.Id)

    function SubmitFormEmployeeSettings(form) {
        $.validator.unobtrusive.parse(form);

                url: form.action,
                data: $(form).serialize(),
                success: function (data) {
                    if (data.success) {
                        PopUp.dialog('close');
                        dataTable.ajax.reload();

                        $.notify(data.message, {
                            globalPosition: "top center",
                            className: "success"
                        })
                    }
                }
            });
        }
        return false;
    }
</script>

这是我的模型。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;

namespace PayrollWeb.Models
{
    public class EmployeeSettingsListModel : BaseModel
    {
        public string EmployeeName { get; set; }
        public TimeSpan EmployeeIn { get; set; }
        public TimeSpan EmployeeOut { get; set; }

    }
}

我不知道为什么数据table在涉及到 TimeSpan 时只显示 Obj Obj。谢谢！

尝试：

....
            var rawData = mployeesetting.ToList().select (b=>new
            {
                Id = b.Id,
                EmployeeName = b.EmployeeName,
                EmployeeIn = b.EmployeeIn.ToString("g"),
                EmployeeOut = b.EmployeeOut.ToString("g"),

            });




            return Json(new { data = rawData }, JsonRequestBehavior.AllowGet);
