14y2.7k.NET

DateTime StartTime = DateTime.Now.ToLocalTime();
DateTime EndTime = DateTime.Now.ToLocalTime();
string dt = EndTime.Subtract(StartTime).ToString().Split('.')[0].ToString();
button1.Text = dt;

starttime = session["logintime"].tostring();

endtime=currenttime...

i have error in retriving the starttime values(ie,session)

if i run this code...it displays the starttime value like 12:00:00

i need this type of output

StartTime:8/7/2010 3:31:16 PM
EndTime:8/7/2010 3:32:00PM

OutPut:

dt=00:00:44

Accepted answer
Dear

You can also use session like this to store date time variable

Store DateTIme
/////////////////////////
DateTime dt;
dt = DateTime.Now();
```
Session.Add("Dtval", dt);
```
//////////////////////////////

Fetch Date Time

DateTime dt = (DateTime)Session["Dtval"];

After you can get diffrence

Dear

dt.ToString("MM/dd/yyyy hh:mm:ss")
Or

String.Format("{0:G}", dt);  // "3/9/2008 4:05:07 PM"

Refer This

DateTime dt = new DateTime(2008, 3, 9, 16, 5, 7, 123);  String.Format("{0:y yy yyy yyyy}", dt);  // "8 08 008 2008"   year String.Format("{0:M MM MMM MMMM}", dt);  // "3 03 Mar March"  month String.Format("{0:d dd ddd dddd}", dt);  // "9 09 Sun Sunday" day String.Format("{0:h hh H HH}",     dt);  // "4 04 16 16"      hour 12/24 String.Format("{0:m mm}",          dt);  // "5 05"            minute String.Format("{0:s ss}",          dt);  // "7 07"            second String.Format("{0:f ff fff ffff}", dt);  // "1 12 123 1230"   sec.fraction String.Format("{0:F FF FFF FFFF}", dt);  // "1 12 123 123"    without zeroes String.Format("{0:t tt}",          dt);  // "P PM"            A.M. or P.M. String.Format("{0:z zz zzz}",      dt);  // "-6 -06 -06:00"   time zone
