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

cast sortable strings and compare. simple and run well.

    return string.Compare(dtOrig.ToString("s"), dtNew.ToString("s"), 
StringComparison.Ordinal) == 0;
