No overload for method 'ToString" takes 1 arguments when casting date
The most immediate way to do this is to write:
DateTime? myDate = form.dteStartDate;
string sqlFormattedDate = myDate?.ToString("yyyy-MM-dd HH:mm:ss") ?? "N/A";
adding ? after myDate will check if it is not null, and with the ?? you will handle the case in which the variable is null.
It will work fine.
DateTime? strDate = form.dteStartDate;
strDate.Value.ToString("yyyy-MM-dd HH:mm tt");
You want to use DateTime.ToString(format)
not Nullable<DateTime>.ToString(no overload)
:
DateTime? myDate = form.dteStartDate;
string sqlFormattedDate = myDate.Value.ToString("yyyy-MM-dd HH:mm:ss");
Of course this doesn't handle the case that there is no value. Perhaps something like this:
string sqlFormattedDate = myDate.HasValue
? myDate.Value.ToString("yyyy-MM-dd HH:mm:ss")
: "<not available>";
string sqlFormattedDate = ((DateTime)myDate).ToString("yyyy-MM-dd HH:mm:ss");
Also if you can use server-side code in .cshtml
and manage this casting as below (for example):
<label>Establish: @(((DateTime)Model.EstablishDate).ToString("yyyy-MM-dd"))</label>
