DateTime start = new DateTime(2015,05,19,11,00,00,00);
DateTime end = new DateTime(2015,05,20,6,00,00,00);
TimeSpan timespan;
timespan = end - start;
double timeDifference = timespan.TotalHours;
Console.WriteLine("Time Difference is :" + timeDifference);

Thanks@Pankit Patel .That code working fine and while how to compare the two dates.

Pankit Patel 19-May-15 3:22am

DateTime start = new DateTime(2015, 05, 19, 11, 00, 00, 00);
DateTime end = new DateTime(2015, 05, 20, 6, 00, 00, 00);
int result = DateTime.Compare(end, start);

date can't able to check. can you tell me the mistake in below code

sstart = DateTime.ParseExact(d1, "dd/MM/yyyy hh:mm:ss tt", null); //start date
eend = DateTime.ParseExact(qw, "dd/MM/yyyy hh:mm:ss tt", null); // current date
efend=DateTime.ParseExact(d2,"dd/MM/yyyy hh:mm:ss tt",null); // end date

int resu = DateTime.Compare(eend,sstart);
int res1 = DateTime.Compare(eend,efend);

if ((resu > 0) && (res1 > 0))
{

//login the user
}
else
{
//block
}

DateTime start = new DateTime(2015, 05, 19, 11, 00, 00, 00);
DateTime end = new DateTime(2015, 05, 20, 6, 00, 00, 00);
DateTime current = new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day, DateTime.Now.Hour, DateTime.Now.Minute, DateTime.Now.Second);
int result = DateTime.Compare(end, start);

string d1 = start.ToString("dd/MM/yyyy hh:mm:ss tt");
string qw = current.ToString("dd/MM/yyyy hh:mm:ss tt");
string d2 = end.ToString("dd/MM/yyyy hh:mm:ss tt");

DateTime sstart = DateTime.ParseExact(d1, "dd/MM/yyyy hh:mm:ss tt", null); //start date
DateTime eend = DateTime.ParseExact(qw, "dd/MM/yyyy hh:mm:ss tt", null); // current date
DateTime efend = DateTime.ParseExact(d2, "dd/MM/yyyy hh:mm:ss tt", null); // end date

int resu = DateTime.Compare(eend, sstart);
int res1 = DateTime.Compare(eend, efend);
if ((resu > 0) && (res1 > 0))
{
//login the user
}
else
{
//block
}

its another working code,

ini = DateTime.ParseExact(d1, "dd/MM/yyyy hh:mm:ss tt", null);
fini = ini.ToString();
q = fini.Split(' ');
fdat = q[0].ToString(); // i get the date here
frem = q[1].ToString(); //hh:mm:ss
rper = q[2].ToString(); /// AM OR pm

ro = frem.Split(':'); // hh:mm:ss tt
rhour = ro[0].ToString();
rpper = Convert.ToInt16(rhour);
rmin = ro[1].ToString();
kq = fdat.Split('/');
rdate = kq[0].ToString(); //date

ssdate = Convert.ToInt16(rdate);

end = DateTime.ParseExact(d2,"dd/MM/yyyy hh:mm:ss tt", null);
exini = end.ToString();
oo = exini.Split(' ');
gdat = oo[0].ToString();
grem = oo[1].ToString();
gper = oo[2].ToString();//pm
// ggper = Convert.ToInt16(gper);
xo = grem.Split(':');
ggdate = xo[0].ToString();
ggper = Convert.ToInt16(ggdate);
gmin = xo[1].ToString();
kg = gdat.Split('/');
gdate = kg[0].ToString(); // end date
eedate = Convert.ToInt16(gdate);

if (ssdate <= cdate)
{

if (eedate >= cdate)
{
}
else
{
alert//start date closed
}
else
{
alert//end date is closed
}
}
