[ASK] C# Namespace Problem

  #1
Nov 1st, 2009
Hi, I've code like this

C# Syntax (Toggle Plain Text) 
  1. namespace RestaurantSoftClassLib.Karyawan
  2. {
  3.    public class Karyawan
  4.    {
  5.        blablabla
  6.    }
  7. }

when I want to use the Karyawan's Class in User's Class
C# Syntax (Toggle Plain Text) 
  1. using RestaurantSoftClassLib.Karyawan;
  2.  
  3. namespace RestaurantSoftClassLib.User
  4. {
  5.     public class User
  6.     {
  7.         Karyawan.Karyawan karyawan;
  8.         blablabla
  9.     }
  10. }

why I used to write Karyawan two times, Karyawan.Karyawan not just Karyawan?

Thanks.

Hello.
That's weird .. works fine for me when I use this:
c# Syntax (Toggle Plain Text) 
  1. using RestaurantSoftClassLib.Karyawan;
and then
c# Syntax (Toggle Plain Text) 
  1. Karyawan karyawan;

Try to remove one Karyawan .. what's happening if you use only one?

if I remove one there is an error like this
"Error 1 'RestaurantSoftClassLib.Karyawan' is a 'namespace' but is used like a 'type' C:\Documents and Settings\sky\My Documents\Visual Studio 2008\Projects\RestoranSoft\RestaurantSoftClassLib\User\User.cs 18 9 RestaurantSoftClassLib"

The confusion comes from the fact that Karyawan is a namespace which contains a class with the name Karyawan.
If you have a namespace A with classes A and B, you would also say A.A and A.B

Put your Karyawan class in the RestaurantSoftClassLib namespace not in the RestaurantSoftClassLib.Karyawan namespace.

Hello.
Or use using directive inside of target namespace:
c# Syntax (Toggle Plain Text) 
  1. namespace RestaurantSoftClassLib.User
  2. {
  3.     using RestaurantSoftClassLib.Karyawan;
  4.     class User
  5.     {
  6.         Karyawan karyawan;        
  7.     }
  8. }

In your code the RestaurantSoftClassLib is visible even without this:
c# Syntax (Toggle Plain Text) 
  1. using RestaurantSoftClassLib.Karyawan;
Because the User namespace is inside RestaurantSoftClassLib . And if you remove this using - there will be no effect. I'm not sure, but suppose that this relationships are more significant and the code, when you're trying to make a reference on RestaurantSoftClassLib.Karyawan is just being ignored.
But since the User is aware of RestaurantSoftClassLib - it has no idea about Karyawan.
So if you restrict the scope of using directive to particular namespace - it would work just fine
