Compare Only Date not the Time (datetimepicker)

[sizar]

Hallo,
i have a problem with comparing two DateTimePickers, which both have the same date.
but with Date.Compare(date1, date2) a voll comparsion with date and time is done.
how can i just compare the dates..
(I have searched the forum and msdn...nothing found)

If you want to get just the date portion of a DateTime object you get its Date property. This returns another DateTime object with the same date but the time portion zeroed to midnight:

Date.Compare(date1.Date, date2.Date)

yes i have been tried this. should work but it didn't..
I solve the problem with taking only the DateValue:
From "15.12.2005 13:25:00" i take just the .SubString(0,10) and compare it..
hope it works

thanks

Why are you dealing with strings? Are you using the Value property of the DTP or the Text property?

Date.Compare(dtp1.Value.Date, dtp2.Value.Date)

If that doesn't work then you are doing something wrong. I recommend against using a hack workaround for a problem that doesn't exist.

sorry with DTP is your suggestion ok.
problem was: that i read my data from sqlerver and datetime-objects are saved with full length (date and time)..that why i play with strings.

A DateTime object is a DateTime object, wherever it comes from. If your query returns date/time values rather than strings then cast them as DateTime objects and use their Date property. Only if your query actually returns strings should you be working with strings.
