Reusing same functions in different .aspx files/making function library
<p>At the moment my website project in asp.NET consists of 5 .aspx files. I have defined the same functions in every .aspx file.
What I want is a way to create my own library/file of functions, which I could include in my .aspx scripts.</p>

<p>While searching for solution I've only found this <strong>Dynamically Including Files in ASP.NET</strong> Which is used to dynamically include HTML and client-side scripts in .aspx. So it's not what I need.</p>
