Pergunta

Is is possible to user Activator.CreateInstance() to instantiate a type given the Type.FullName and Assembly Name even though the assembly is not referenced by the executing assembly?

Solução

Yes, first you have to load the assembly.

Suppose you have a "plugins" folder to look into:

            foreach (FileInfo f in new DirectoryInfo("c:\\plugins").GetFiles("*.dll"))
            {
                System.Reflection.Assembly.LoadFrom(f.FullName);
            }

Now assemblies are loaded and you can create the type using Activator.CreateInstance.

Yup. That is the beauty of Reflection. You can load the assembly by knowing it's name and then you can create a type that is declared within that assembly.
