模块VB.Net中的命名空间(Namespace in module VB.Net)

 我想知道是否有任何方法可以将命名空间（或类似的东西）放入模块中，仅用于代码排序，如下所示： 
 
Public Module1

    Namespace N1 (or whatever)

        Public N1_1 as integer = 45    

    End Namespace

    Namespace N2 (or whatever)

        Public N2_1 as integer = 28

    End Namespace


End Module
 
 那么我可以这样做： 
 
Module1.N1.N1_1
 
 谢谢！ 
 
 编辑：值必须能够更改，所以我不能使用枚举 

I would like to know if there is any way to make a namespace (or something like that) into a module, is just for code sorting, something like this:
 
Public Module1

    Namespace N1 (or whatever)

        Public N1_1 as integer = 45    

    End Namespace

    Namespace N2 (or whatever)

        Public N2_1 as integer = 28

    End Namespace


End Module
 
So then I can do:
 
Module1.N1.N1_1
 
Thanks!
 
Edit: values must be able to be changed so I can't use Enum
