Help w/ Namespaces/Classes

[stillinlife101]

I want to write a series of namespaces and classes that look something like this:

namespace a
{
class a
{
public int DoSomething()
{
}
}
namespace b
{
class b:a
{
public int DoSomethingAlso()
{
}
}
}
}

and then be able to declare something as such:

a.b NewVar = new a.b();
NewVar.DoSomething();
NewVar.DoSomethingAlso();

Is something like that possible, and if so, could somebody give me a template? Thanks,

Dan

You generally don't want to name the class the same as your namespace, because then you get fully qualified names like a.a and b.b, which is confusing.

There's two ways to go -- you can fully-qualify the name of a inside the b namespace:

using System;

namespace b
{
  public class b : a.a
  {
    public b()
    {
    }
  }
}

or use an using statement, which allows you to use shortcut names:

using System;
using a;

namespace b
{
  public class b : a
  {
    public b()
    {
    }
  }
}

How do you nest namespaces? I'm working on something that will require a hierarchy of namespaces, sort of like the System namespace in .Net. System.H1.H2.H3... etc How do I create those nested namespaces so that I can

1) use the hierarchy to find my class and
2) inherit from higher level classes? (all namespaces should inherit from the parent namespace, i.e. H2 inherits from H1, etc)

You would create nested directories and/or projects under your solution. By setting the default namespace at the project level (project properties), VS.NET will automatically create the correct namespace whenever you add a new class.

If you have multiple namespaces within a project, you can create folders in your VS.NET project (right-click, add new folder). You'll get the same nested namespace, and nested directory structure, but it'll all be in one assembly when it gets built.
