Including or importing Source files?

[Ryan Knopp]

Do I have to compile a class to be able to import it into another source?

Can I do something like

include System;
include System.IO;
include Language; <-- language is a Language.cs file. Does this file
need to be a dll or can i just include the source? I get compile errors
doing this but maybe there was a way around it.

thanks

Hi

You need to include the namespace which contains the .cs file and not the .cs file itself

e.g. Let yuor .cs file be
namespace TEM

class temp

int a



In the document in whcih you want to include, the using header will b
using System.IO
using System.*
using TEMP

HI

Forgot to add

If the .cs file is inside your DLL/EXE, then compiling will not be required. else, you will need to compile t

Sounds like ya mixing up 3 different things:
-referencing other class.
-including a namespace
-referencing a dll\project

If in class A you want to reference class B then:
-If class B is in same namespace and same dll\project -> do nothing
-If class B is in other namespace in same dll\project -> include
namespace
-if class B is in other dll\project but same namespace -> Add
reference to dll that contains class B. If also other namespace ->
also include namespace.

Normally you do not compile one single class to a dll, but coherent
set of classes.

Think your case is the simplest one and you don't have to import
anything. You get the compile error because you try to includ a class
(Language), which is neither allowed, nor needed (as long as you are
in same namespace or do not use namespaces at all).

I believe the real question Ryan is asking is if can do macro expansion includes (i.e. similar to server side includes in web app development or the way C uses the include <stdio.h> macro. C basically makes a copy of the text in stdio.h and puts it in the place of the line include <stdio.h>. I believe the reason Ryan is probably asking this is to allow him to change the definition of some code and/or resource at runtime. This can't be done this way in .NET. You need to either use Codedom namespace to dynamically generate code, use dynamic binding and a config file (see System.AddDomain for more info) to load dlls at runtime, use config file to store runtime specific info, or use resource files to store locale/environment specific info that can change at runtime. If this is not the reason you were wanting this ability reply with more info about what you're trying to do

FYI - a new feature in the next release of C# is partial classes. This will allow you to split up the definition of a class in multiple files. Check it out it's pretty cool. Whidbey will also be having a realtime refreshed class modeler where updates to the model will be instantly refreshed in the code and vice versa. Pretty cool in deed

As a side note, the splat used in Vipul's first post (System.*) does not work in .NET that's Java. In Java you had to import classes not namespaces (packages) so the splat was used to import all classes in a package. So there isn't really any need for splat in .NET.
