Finding a class in an assembly?

[Satch]

My program compiles script files written in VB.NET at run-time into an assembly in memory using the built-in compiler stuff. Now, let's say my script has this in it:

Namespace Testing
    Public Class Abc
        Public Sub TryMe()
            System.Windows.Forms.MessageBox.Show("Hello World")
        End Sub
    End Class
End Namespace

Well, my program will take this script and compile it at run-time into an assembly in memory.

Is there a way to get a list of the namespaces/classes/etc. contained within the assembly, or search through it for a class with a certain name and return its information?

I'm pretty new to assembly stuff and compiling dynamic code at run-time, so I'm not really sure how to do much yet. Any help would be greatly appreciated.

Thanks in advance,
Satch
