Ignore milliseconds when comparing two datetimes

Question

I am comparing the LastWriteTime of two files, however it is always failing because the file I downloaded off the net always has milliseconds set at 0, and my original file has an actual value. Is there a simple way to ignore the milliseconds when comparing?

Here's my function:

//compare file's dates
public bool CompareByModifiedDate(string strOrigFile, string strDownloadedFile)
{
     DateTime dtOrig = File.GetLastWriteTime(strOrigFile);
     DateTime dtNew = File.GetLastWriteTime(strDownloadedFile);
            
     if (dtOrig == dtNew)
        return true;
     else
        return false;
}

Answer 1

Create a new DateTime value with the milliseconds component set to 0:

dt = dt.AddMilliseconds(-dt.Millisecond);
