How can I get the next month End Date from the given Date
<p>I am implementing a code to find quarter start date and End date every thing was implemented fine but if user enters a date like <code>2011,2,1</code> I would like to get the <code>quarter</code> end date based on this date  </p>

<pre><code>DateTime dtTempStartDate = new DateTime(2011, 2, 1);
var qrtrDate = DateTime.ParseExact(dtTempStartDate.ToString("MM-dd-yyyy"), "MM-dd-yyyy", System.Globalization.CultureInfo.InvariantCulture);
var dtMnthEnd = qrtrDate.AddMonths(1);` 
</code></pre>

<p>should I add <code>days</code> or <code>add milliseconds</code> can some one help me...</p>
