使用 Linq 到 Datatable 顯示日期時間的最佳方法是什么？

Question

我有一個 linq select 一些列，其中包含數據表的日期。 我正在使用 ASP MVC 5 和 Datatble。

我真的需要日期時間。 我已經顯示字符串並且沒有問題。 但是當我嘗試顯示原始日期時間時，我得到了這個 output

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

這是我的代碼

 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;

我通過視圖中的 ajax 調用獲得結果。 這沒有問題，除了顯示上述錯誤的日期時間列

我需要像我在 SQL 服務器 08/10/2019 10:43 中看到的東西

要按預期顯示，您必須將日期轉換為字符串。 前任。 string.Format（“{0：G}”，費用.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,
                                       });

我找到了解決我的問題的方法。 請注意，這可能不是唯一的解決方案，但正是我想要的。 解決方案是使用 moment.js，這就是我呈現列的方式，一切正常。 我希望保留原始數據及其類型（日期時間）。

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