Hi,

I want to pass datetime value from application to stored procedure (SP).

Last login date of user is stored in session variable and i want to pass it in SP.

i am doing it like this-

C#

DateTime myDt = DateTime.ParseExact(Session["Last_Login_date"].ToString(), "yyyy-MM-dd", System.Globalization.CultureInfo.InvariantCulture);

but i am getting error-

C#

String was not recognized as a valid DateTime.

My Session["Last_Login_date"] contains date - "30, Jun 2014 12:08: PM"

Should i need to change format and assign?
Please help

Solution 3

Try this:

DateTime dt = DateTime.ParseExact("30, Jun 2014 12:08 PM", "dd, MMM yyyy hh:mm tt", CultureInfo.InvariantCulture);

Before this, make sure your date format is appropriate as specified in the string underlined above.

Solution 1

try with

C#

DateTime myDt = Convert.ToDateTime(Session["Last_Login_date"]);

if you going to use DateTime.ParseExact then you need to give exact format as your input, otherwise it will fail.
Set session value with DateTime object directly.

C#

Session["Last_Login_date"] =DateTime.Now;

when you need to retrieve value back,

C#

DateTime myDt = Convert.ToDateTime(Session["Last_Login_date"]);
