Ignore milliseconds when comparing two datetimes

Question

This is probably a dumb question, but I cannot seem to figure it out. I am comparing the LastWriteTime of two files, however it is always failing because the file I download

Answer 1

You could create an extension method that would set the milliseconds to zero for a DateTime object

public static DateTime ZeroMilliseconds(this DateTime value) {
  return new DateTime(value.Year, value.Month, value.Day, 
    value.Hours, value.Minutes, value.Seconds);
}

Then in your function

 if (dtOrig.ZeroMilliseconds() == dtNew.ZeroMilliseconds())
        return true;
     else
        return false;
