How do I convert timespan method to decimal?
<p>Here is my code:</p>

<pre><code>TimeSpan span1 = TimeSpan.FromHours(dtmIn.Value.Hour);
TimeSpan span2 = TimeSpan.FromHours(dtmOut.Value.Hour);
TimeSpan span3 = TimeSpan.FromMinutes(dtmIn.Value.Minute);
TimeSpan span4 = TimeSpan.FromMinutes(dtmOut.Value.Minute);
TimeSpan span5 = span2.Subtract(span1) + span4.Subtract(span3);

lblTotal.Text = Convert.ToDecimal(span5).ToString("#.00");
</code></pre>

<p>I get a formatting error for the last line. I can get the label to return as time obviously, but I need it to return as a decimal.</p>
