使用 Linq to Datatable 显示日期时间的最佳方法是什么？

Question

我有一个 linq，可以选择一些带有日期的列到数据表。 我正在使用 ASP MVC 5 和 Datatble。

我真的需要日期时间。我已经显示字符串并且没有问题。 但是当我尝试显示原始日期时间时，我得到了这个输出

/Date(1569366000000)/   /Date(1569397607057)/

这是我的代码

 var IQueryabletimesheet = (from expense in _context.ExpenseModel
                                       join expenseaudittb in _context.ExpenseAuditTB on expense.ExpenseID equals expenseaudittb.ExpenseID
                                       join project in _context.ProjectMaster on expense.ProjectID equals project.ProjectID
                                       join registration in _context.Registration on expense.UserID equals registration.RegistrationID
                                       join AssignedRolesAdmin in _context.AssignedRoles on registration.RegistrationID equals AssignedRolesAdmin.RegistrationID
                                       where AssignedRolesAdmin.AssignToAdmin == UserID && expenseaudittb.Status == 3
                                       select new ExpenseModelView
                                       {
                                           ExpenseID = expense.ExpenseID,
                                           ProjectName = project.ProjectName,
                                           RequestBy = registration.Name,
                                           FromDate = expense.FromDate.Value,

                                           ProcessedDate = expenseaudittb.ProcessedDate,

                                           ExpenseStatus = expense.ExpenseStatus == 1 ? "Submitted" : expense.ExpenseStatus == 2 ? "Approved" : expense.ExpenseStatus == 4 ? "Pending Final Approval" : "Rejected",

                                           PurposeorReason = expense.PurposeorReason,
                                           TotalAmount = expense.TotalAmount,

                                           VoucherID = expense.VoucherID,
                                       });

            if (!(string.IsNullOrEmpty(sortColumn) && string.IsNullOrEmpty(sortColumnDir)))
            {
                IQueryabletimesheet = IQueryabletimesheet.OrderBy(sortColumn + " " + sortColumnDir);
            }
            if (!string.IsNullOrEmpty(Search))
            {
                //IQueryabletimesheet = IQueryabletimesheet.Where(m => m.FromDate == Search);
            }

            return IQueryabletimesheet;

我通过视图中的 ajax 调用获得结果。这没有问题，除了显示上述错误的日期时间列

我需要类似于我在 SQL Server 中看到的东西 2019 年 8 月 10 日 10:43

Answer 1

我找到了解决问题的方法。请注意，这可能不是唯一的解决方案，但正是我想要的。解决方案是使用 moment.js，这就是我呈现列的方式，一切正常。我希望保留原始数据及其类型（日期时间）。

{
   title: "ProcessedDate",// name 
   render: function (data, type, row) 
            {//data
                        return moment(row.ProcessedDate).format('DD/MM/YYYY hh:mm:ss');
            }
}           

Answer 2

要按预期显示，您必须将日期转换为字符串。前任。 string.Format("{0: G}",费用.FromDate.Value)。

var IQueryabletimesheet = (from expense in _context.ExpenseModel
                                       join expenseaudittb in _context.ExpenseAuditTB on expense.ExpenseID equals expenseaudittb.ExpenseID
                                       join project in _context.ProjectMaster on expense.ProjectID equals project.ProjectID
                                       join registration in _context.Registration on expense.UserID equals registration.RegistrationID
                                       join AssignedRolesAdmin in _context.AssignedRoles on registration.RegistrationID equals AssignedRolesAdmin.RegistrationID
                                       where AssignedRolesAdmin.AssignToAdmin == UserID && expenseaudittb.Status == 3
                                       select new ExpenseModelView
                                       {
                                           ExpenseID = expense.ExpenseID,
                                           ProjectName = project.ProjectName,
                                           RequestBy = registration.Name,
                                           FromDate = string.Format ("{0:G}", expense.FromDate.Value),

                                           ProcessedDate = expenseaudittb.ProcessedDate,

                                           ExpenseStatus = expense.ExpenseStatus == 1 ? "Submitted" : expense.ExpenseStatus == 2 ? "Approved" : expense.ExpenseStatus == 4 ? "Pending Final Approval" : "Rejected",

                                           PurposeorReason = expense.PurposeorReason,
                                           TotalAmount = expense.TotalAmount,

                                           VoucherID = expense.VoucherID,
                                       });
