Ignore milliseconds when comparing two datetimes

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 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;
}


Thanks in advance

Answer

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

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