List all classes in .NET

[martin]

Hi,

I have some rather unusual questions?

How do I list/enumerate all classes in a namespace?
How do I list/enumerate all classes in a assembly?
How do I list/enumerate all classes in .NET?

For the last part I guess I would enumrate the files in the GAC or something
and then work from there? But how can I load information about a particular
..NET .DLL file given that I know where it's located on disk? Does every .DLL
file contain exactly one assembly and/or namespace or how does it work?

Someone might wonder _why_ I would want to do this.. Basically, I'm just
gonna generate some statistics out of curiousity.


regards,
martin

Reflection is your friend!

Check out the System.Reflecti on and System.Reflecti on.Emit namespaces for
classes that will do what you are asking.

Hello martin,

You can use reflection (System.Reflect ion) for what you need starting
at the assembly level. From there you can query the entire assembly for
declared types.

The class System.Reflecti on.Assembly provides methods do load an
assembly (by name, file etc) and get the types by GetTypes();

(GetReferencedA ssemblies).

For the namespace part you will have to add some logic because there is
no direct way to get all the types defined in a namespace.

Read in the Assembly using the Assembly.Load or Assembly.LoadFi le
methods. Then call the GetTypes() method on that assembly, and
enumerate through the array of Type objects it returns. Each type
object should have all the information you need.

There no real way of doing this, as a namespace could easily be spread
out over multiple assemblies. You just have to use the above method
for each assembly, and sort the results by namespace.

You will have to include a reference to ALL the assemblies.

You could also load them dynimically
