Create commonly used method for asp.net website

Question

Is it possible to create a function that can be called by multiple different pages in asp.net?

Say for example I have a method that takes two int parameters and adds them together and spits out the result

public int test(int a, int b)
{
     return a+b;
}

If I wanted to use this function on three different pages, how would I do it?

notes: using C# .NET 4 Entity Framework

Answer 1

This method can be made static and you can put such methods into a static class like this.

public static class Utils
{

    public static int test(int a, int b)
    {
         return a+b;
    }

}

can call it from any page.

int result = Utils.test(someA, someB);

The other option is, if it's some page oriented function, you could create your own class that extends Page class and add function there and if you make all your pages extend this custom class, the functions will be available.

public class MyPage : Page
{

    public int test(int a, int b)
    {
         return a+b;
    }

    ....
}

Two options that make the most sense to me would be to:

1. Create a public static class like Common or Utils .
2. Create a BasePage that inherits from System.Web.UI.Page , and have your three pages inherit from the BasePage, which contains your test() method.
