Question

How can I get a class into a variable to call function and get properties?
I have been told to look into reflection but I don’t get how it’s done when the DLL was not known at compile time.

To be clear: I have a ‘main’ class which loads an DLL and I want to create an instance of a class within the DLL and directly get properties.

You should do something like this:

Assembly asm = Assembly.Load("DLL File Path"); //load DLL from file
Type t = asm.GetType("Test.ExternalDllTest"); //fully qualified name
dynamic oDynamic = Activator.CreateInstance(t, args);//create an instance of specified type, and assign it to DYNAMIC object

EDIT

 oDynamic.SomeMethod(); //call the method of your type. Being DYNAMIC it will route the call to correct method.

Naturally, the DLL has to be a managed DLL (so written in .NET language)

I didn’t compile this, honestly, but basically this is an idea of how to do that.

Here also an example, that may help.
