DateTime TryParse problem
<pre><code>string date = txtWorkingDate.Text;
            DateTime dateTime = DateTime.MinValue;

            if (DateTime.TryParse(date, out dateTime))
            {
                args.IsValid = true;
            }
            else
                args.IsValid = false;
</code></pre>

<p>txtWorkingDate.Text is like "dd.MM.yyyy" becouse of this validateion is always false if date is not like "dd.MM.yyyy". How c an i check types of date like "dd.MM.yyyy", "MM/dd/yyyy" becouse are all valid.</p>
