Question

I want to compare two dates. In pseudo-code:

If the dueDate > now or dueDate = now 

Then Fine Amount = something.

Else Fine Amount = 0

I wrote below code:

DateTime dueDate = Convert.ToDateTime(Reader1[3].ToString());
DateTime now = DateTime.Now;
int result = DateTime.Compare(dueDate, now);
if ((result < 0) || (result == 1))
{
    row["Fine_Amount"] = Convert.ToDouble(Reader1[4].ToString()); 
}
else
{
    row["Fine_Amount"] = 0;
}

This code gives wrong value, when

dueDate = 23-12-2011 AM 12:00:00
now = 23-12-2011 PM 05:26:54

I want to Compare:

dueDate = 23-12-2011
now = 23-12-2011

How do I remove the time in that?.

Adding below code is given result. But its to lengthy code.: –

 DateTime dueDate = Convert.ToDateTime(Reader1[3].ToString());
                    DateTime now = DateTime.Now;

                    if (dueDate.Year < now.Year)
                    {
                        row["Fine_Amount"] = Convert.ToDouble(Reader1[4].ToString());
                    }
                    else if (dueDate.Year > now.Year)
                    {
                        row["Fine_Amount"] = 0;
                    }
                    else if (dueDate.Year == now.Year)
                    {
                        if (dueDate.Month < now.Month)
                        {
                             row["Fine_Amount"] = Convert.ToDouble(Reader1[4].ToString();
                        }
                        else if(dueDate.Month > now.Month)
                        {
                             row["Fine_Amount"] = 0;
                        }
                        else if(dueDate.Month == now.Month)
                        {
                             if(dueDate.Day < now.Day)
                             {
                                 row["Fine_Amount"] = Convert.ToDouble(Reader1[4].ToString();
                             }
                             else
                             {
                                 row["Fine_Amount"] = 0;
                             }
                        }
                    }

Is there any way to short this code?.

Answer For this Question is

if (dueDate.Date >= now.Date)
{
    row["Fine_Amount"] = 0;
}
else
{
    row["Fine_Amount"] = Convert.ToDouble(Reader1[4].ToString());
}

This datetime.date is gives

 dueDate = 23-12-2011 AM 12:00:00 to 23-12-2011 AM 12:00:00 
    now = 23-12-2011 PM 05:26:54 to 23-12-2011 AM 12:00:00 

Answer 1

You can use DateTime.Now.Date

According to docs, Date property returns: A new object with the same date as this instance, and the time value set to 12:00:00 midnight (00:00:00).
