Man, looks like there are a hundred ways of achieving this thing. I'm
feeling more and more embarresed I could find a single one one my own...
Thanks,
David

Return a list of types in the assembly:
Assembly.GetExecutingAssembly().GetTypes()
Test if a type implements an interface
if( typeof(IYourInterface).IsAssignableFrom(type) ) {
Create an instance:
Activator.CreateInstance( type, new object[] { any, parameters, the, ctor,
needs } )

Subject: [ADVANCED-DOTNET] Searching classes in an assembly
Hello all,
I've been wondering how to do something tricky, and I
can'tfind a single reference about it in the msdn docs...
Imagine I have a regular windows program, with a bunchof
classes that all implement a certain interface. There are
also lots of other classes that do not implement it.
The interface defines a readonly property called Name which
returns the name of the class.
Now I would like add a textbox, where the user can type a
string at runtime, and then the app has to find (and
initialize) the class which name equals the entered text.
But for this to work I need to do 2 things I can't find:
1) search an assembly at runtimefor classes that implement an
interface
2) create an instance of a class using a variable type (or don't I?)
Any thoughts on how to approach this?
