Hi All,
I've created a PluginManager assembly, using the one in 'The CodeProject'
as a base. My understanding of the plugin manager is that it dynamically
picks up types in an assembly (by watching the plugin directory) and then
makes the type available within the main AppDomain.
How it achieves this is slightly off topic but I think it creates a
temporary AppDomain and then 'copies' the type into the main one from
there.
My problem is that what I end up with is not the type itself but a proxy
to it. Should I try to call any of the methods of the type (by casting
from to the type I want) I get an error: "Cannot obtain fields or call
methods on the instance of type 'My.Type.Name' because it is a proxy to a
remote object".
The type I am attempting to load in inherited from an abstract class held
in assembly that is referenced throughout the app. The abstract class
inherits from MarshallByRefObject.
Code snippet:
string typename = "MyTypeName"; // where this type inherits
from 'MyTypeBase'
MyType obj = PluginManager.CreateInstance("MyTypeName",
System.Reflection.BindingFlags.CreateInstance, new string[] { });
// Error on next line
obj.SimpleMethod(); // where SimpleMethod is a virtual method from
MyTypeBase
I'm using VS 2005 / c# / .Net 2.0
Driving me mad so any suggestions very welcome!
Kind regards,
Graeme
