bool equal = dt.AddSeconds(-dt.Seconds) ==datetimepeicker1.value.AddSeconds(-datetimepeicker1.value.Seconds) - Marked As Answer byLinda LiuMSFT, ModeratorWednesday, April 01, 2009 3:53 AM

If you only want to compare the Year, Month and Day part of two DateTime value, you can opt to the following two methods except the way Christoph has suggested.
1. Construct new DateTime values based on the Year, Month and Day parts. For example:
DateTime dt = DateTime.Now;
DateTime dt1 = new DateTime(dt.Year, dt.Month, dt.Day);
DateTime dt2 = new DateTime(this.dateTimePicker1.Value.Year, this.dateTimePicker1.Value.Month, this.dateTimePicker1.Value.Day);
if (dt1 == dt2)
{
....
}
2. Compare the Year, Month and Day parts of the two DateTime values respectively. For example:
DateTime dt = DateTime.Now;
if (dt.Year == this.dateTimePicker1.Value.Year && dt.Month == this.dateTimePicker1.Value.Month && dt.Day == this.dateTimePicker1.Value.Day)
{
...
}
