Hello,
Since I am learning C# now, I might have a simple question, I know my
datarow dr[myDate] keeps datatime and I need to compare it if it is current
date, if not how many days ago? How should I compare date and find how many
day difference?
Thanks,
Jim.
 
Assuming your date in the row is XXX as a DateTime object:

TimeSpan ts = DateTime.Now - XXX;

Now you can look at ts properties such as TotalMinutes, etc.

Thanks for the reply.
DateTime sDate=System.Convert.ToDateTime(dr["myDate"]);

TimeSpan ts = DateTime.Now - sDate;
int tHours=ts.Hours;
int tDays=ts.Days;

This is working fine to see discrepancy in hours. Now I only need to compare
date part of DateTime for both dr["myDate"] and DateTime.Now. how should I do
this?
Thanks,
Jim.

DateTime sDate=System.Convert.ToDateTime(dr["myDateTime"]);

if (sDate.Date < DateTime.Now.Date)
{
debug= "Warning: old date!";
}

do you see any problem with this comparision, it seems it is working?
Thanks,
Jim.

Hi Jim,

You would use the methods of the DateTime object:
