Reflection help needed...

[AlexCode]

Hi.

 

I'm trying to do something I don't know if it's possible... ;)

 

I need to access objects declared on an assembly (class2) from the main class (class1), at runtime, but the only link between them its an Interface.

So I don't really know what objects exist on the 'class2'.

 

The class2 implements the Interface.

The Interface have 1 method:

- Public function GetObject(name as string) as object

 

The implementation of this Interface on class2 goes like the following:

           For Each obj As Object In Me.GetType.GetFields
               If TypeOf obj Is System.Reflection.FieldInfo Then
                   If CType(obj, System.Reflection.FieldInfo).Name = "t" & name Then
                        'Found the FieldInfo
                   End If
               End If
           Next

 

So, calling the GetObject function, I can retrieve the FieldInfo of a field inside a class, by reflection, by its name.

The problem is that I don't what the field info... I want the actual object.

 

On the NEW of the class2 I instanciate several objects.

If class2 were referenced normally, intellisense would just give me the objects, but thru the interface I can't have them that way.

 

I can use the Assembly.CreateInstance but this will create another instance of the same object, not the already created instance on class2.

 

 

So, is there a way to do this?

 

Thanks,

Have you looked here for a sample in how to dynamically load classes via a standard interface?

[AlexCode]

That's exactly the way I've been doing it for several months now...

 

The problem is that this way I can only create new objects (classes) and know all the methods in them thru the Interface.

 

What do I have:

 

I have a class that's created thru CodeDOM, compiled at runtime and recognized by the main application as a PlugIn.

The methods in the plugin class are variable.

I need a way to get them by name.

 

This is crazy I know eheheh, but I'm crazy!, and this crazy idea lets me create a database at runtime, changing the look and functionalities of my application directly on the client. The application builds itself from an XML or sevelar XML files and plugins assemblies... becoming a huge ERP... :p
