You need to provide more information. Is this Windows Forms ?

What action by the user triggers your evaluation of the content of the two Text Boxes ?

Solution 1

ASP.NET

Small number:<br />
<asp:TextBox runat="server" id="txtSmallNumber" /><br /><br />
Big number:<br />
<asp:TextBox runat="server" id="txtBigNumber" /><br />
<asp:CompareValidator runat="server" id="cmpNumbers" controltovalidate="txtSmallNumber" controltocompare="txtBigNumber" operator="LessThan" type="Integer" errormessage="The first number should be smaller than the second number!" /><br />

What if the inquirer is talking about Windows Forms or WPF? What if, in your solution, someone enters text instead of numbers?

Solution 2

Change the TextBoxes to NumericUpDowns. They guarantee to have a number available in the Value property.
