Question

I have a datetime object, dt, that holds today’s date.

DateTime dt = DateTime.Today;
DateTime idt = new DateTime();

I need to print the date when the loop reaches last day of the current year, like this:
345 more days to 12/31/2012

If I do it this way

while (dt.AddDays(i).Year == dt.Year) 
{
    idt = dt.AddDays(i);
    i++;
}
Console.WriteLine("{0} more days to {1}", i, idt.ToString("d")); 

I am able to get it to print like I want: 345 more days to 1/1/2012

I want to avoid the repetition of dt.AddDays(i) in the above part. If I do it either this way:

while (idt.Year != dt.Year + 1)
{
    idt = dt.AddDays(i);
    i++;
}
Console.WriteLine("{0} more days to {1}", i, idt.ToString("d"));

or this way:

while (idt.Year < 2013)
{
    idt = dt.AddDays(i);
    i++;
} 
Console.WriteLine("{0} more days to {1}", i, idt.ToString("d"));

I get the output as 346 more days to 1/1/2013.

I am definitely missing something painfully obvious, but I am unable to figure out. What would it be?

Why not just

int days = new DateTime(dt.Year, 12, 31).Subtract(dt).Days;

?
