C# multiple files

They are both, right now, in the MyFormProject namespace; that is, I put "namespace MyFormProject" at the beginning of each file and included all the code under it.

That's not quite clear. Do you merely declare the namespace (namespace MyFormProject;) or do you define the class within the namespace (namespace MyFormProject { <class definition> })?

Secondly, if I have a class named MyClass, does it HAVE to be in MyClass.cs?

No. Nor do you have to have only one class per .cs file.

What's the rule on that, and naming conventions for C# in general.

There might be something in the C# FAQ

Thank you for your very helpful replies, first off. I very much like that second link.

Anyways, I did this in my MyClass.cs file:

namespace MyFormProject
{
class MyClass
{
public void MyFunction()
{ ... }
}
}

My MainForm.cs file has the code the compiler set up for me when I made my form, for the most part. It is also, in the same way, by default though, in the MyFormProject namespace. I copied that idea into my MyClass.cs file exactly, hoping that would solve my problem. It didn''t. Same missing namespace or assembly listing error.

In MainForm.cs I do this:

MyClass bob = new MyClass();
...
bob.MyFunction();

And there is where I get the error. I''ve tried messing around with namespaces quite a lot. I''ve looked through my books as well. Using statements? I don''t think so, but I''ll ask.

I''m sure someone here has used more than one .cs file in a project. How do you do it?

Thanks again.

Your code seems fine, and you say both files are in the combine (using SharpDevelop?)

Could you just post the full error message, along with the portion of MyForm.cs where you reference MyClass? Scope and typos are the only things that come to mind at this point.

Put this:

MyClass bob = new MyClass();
...
bob.MyFunction(); 

in the MyFormProject, too. Then, MyClass will be able to access other classes in its namespace.

Your code should look something like this:

MyForm.cs

using Forms = System.Windows.Forms;

namespace MyFormsProject {
  class MyForm : Forms.Form {
    // member declarations


    public MyForm() {
      InitializeComponent();
      // any other initialization

    }

    void InitializeComponent() {
      // initialize form

    }

    [STAThread]
    public static void Main(string[] args) {
      Application.Run(new MyForm());
    }
  }
}

MyClass.cs

 
namespace MyFormProject {
  class MyClass {
    public MyClass() {
      // _ctor

    }

    public void SomeFunction() {
      // blah

    }
  }
}

The statements

MyClass bob = new MyClass();
...
bob.SomeFunction();  

need to occur within a method in MyForm.

You can do that?

Oh yeah!
