hi ,

your code is giving the correct answer. no or days between current day and input day.
so what the problem you are getting.

            TimeSpan ts = new TimeSpan();
            double s1;
            double s2;
            DateTime dt = System.DateTime.Today;
            DateTime dt1 = dtpDate.Value;
            ts = (dt - dt1);
            s1 = Convert.ToDouble(ts.TotalDays);
            //s2 = Convert.ToDouble(ts.TotalMinutes);
            txtTotDays.Text = Convert.ToString(s1);  
i not need to subtract time.i need date to subtract from datetime

try this: date in mm/dd/yyyy format

 DateTime d1=Convert.ToDateTime("12/22/2013");
 DateTime d2 = Convert.ToDateTime("12/22/2012");
 var d = (d1 - d2).TotalDays;


output:365

in C# i not need to subtract time from datetime.take date only to calculate number of days

how to take date from datetime to subtract when i using that code subtracting number of days not coming correct manner

Hi,
        Can you provide your example?

i not need to subtract time format, how to take date from datetime format to subtract and know to calculate number of days

try this :

TimeSpan difference = dateTime1 - dateTime2;

difference.TotalDays will give you number of days

var days = difference.TotalDays;
