hi

I use below code to enter date into text box:

    <script type="text/javascript">
        $(function () {
            $("#TxtdateC").mask("0000/00/00");
            $("#TxtdateE").mask("0000/00/00");
            $('[id*=TxtdateC]').on("change", function () {
                var reg = /^(13|15)\d\d[\-\/.](0[1-9]|1[012])[\-\/.](0[1-9]|[12][0-9]|3[01])$/;
                if (!reg.test($('[id*=TxtdateC]').val())) {
                    alert("Please enter valid date format");
                    $('[id*=TxtdateC]').val('');
                    $('[id*=TxtdateC]').focus();
                }
            });

            $('[id*=TxtdateE]').on("change", function () {
                var reg = /^(13|20)\d\d[\-\/.](0[1-9]|1[012])[\-\/.](0[1-9]|[12][0-9]|3[01])$/;
                if (!reg.test($('[id*=TxtdateE]').val())) {
                    alert("Please enter valid date format");
                    $('[id*=TxtdateE]').val('');
                    $('[id*=TxtdateE]').focus();
                }
            });
        });
     
    </script>

here user can enter date to shamsi like:

1396/02/19

now I  want when they click button to save this date into database it will save this date to 2017-09-17 into database

I test this code:

 System.Globalization.PersianCalendar shamsi = new System.Globalization.PersianCalendar();
DateTime startDate = new DateTime(int.Parse(TxtdateC.Text), shamsi);

but this error happen:

Server Error in '/' Application.
