Using external files in C#...

Question

I am trying to create something similar to VB modules. Do I have to create a DLL or can I just call classes from another .CS file? I've tried pulling from a CS file but I get the error that I need to set an entry point. I've added the namespace at the beginning. The example below is roughly what I'm trying to do I can see the functions from the other file I just keep getting that error on compile. using Example.test //Windows form stuff... public void myFunction() { myClass mC = new myClass(); label1.Text = mC.stuff().ToString(); } thanks Jason

Maybe its just the example I was using. I'll try writing my own. I had found a class for generating better random numbers. Their example didnt use a form though it called the class into the main CS file which seemed to be a console program. I tried to add it to my project but got that error message when it compiled. I used the namespace and saw the classes. Thanks I'll see what happens when I do one from scratch.

I don't know how that happens.. You're just trying to write a reusable class in a separate file right? In visual studio you just click Project -> Add Existing Item -> Browse to desired .cs file. You then set USING NAMESPACE; and start calling its functions.
