Generate DateTime

Hi I want to generate tommorrow's datetime,time 8:00:00 AM
I tried generating the date like this:
DateTime dtNow = new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day+1, 8, 0, 0, 0);
It fails if it trys to generate date on i.e. APR 30, because there is no APR 31, so it crushes, what would be another way of generating next days date,time
 
thanks,
...
