title: Ignore milliseconds when comparing two datetimes
body: <p>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?</p>
  
  <p>Here's my function:</p>
  
  <pre><code>//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;
  }
  </code></pre>
  
  <p>Thanks in advance</p>
