Front End Code:
5 <fieldset>
6 <legend>Double.Parse() vs. Convert.ToDouble()</legend>
7 This will convert a string number (5435.523) to a double 100,000 times.

10 <br />
11 End Time : <asp:Literal ID="litEnd1" runat="server" />
12 <br />
13 <h4>Convert.ToDouble()</h4>
14 Start Time: <asp:Literal ID="litStart2" runat="server" />
15 <br />
16 End Time : <asp:Literal ID="litEnd2" runat="server" />
