How to use separate .cs files in C#?

Question

Forum; I am a newbie working out a bit of code. I would like to know the best way to use separate .cs files containing other classes and functions. As an example of a basic func

Answer 1

It is fairly simple to do. In your btClear.cs file simply generate a class definition like:

public class MyUtility
{
    public static void ClearContents(IEnumerable controls)
    {
        //TODO: Code that clears contents of controls passed
    }
}

Then you can call it from wherever the namespace the generated class is contained in is referenced via:

MyUtility.ClearContents(SomeControlCollection);

I hope I didn't completely miss the mark on your intention.
