Is there a simple way of getting the .NET type of an IronRuby class?

I have this code:

resources =  
System::ComponentModel::ComponentResourceManager.new(X.class)

where X is a class. But this doesn’t do it - I get a run time exception.

Any ideas?

Thanks! Yes, it’s obvious: I think I’ve got trouble switching beteen  
thinking in Ruby and thinking in .NET …

resources = System::ComponentModel::ComponentResoruceManager.new(  
X.GetType)

or if you’d rather:

require ‘mscorlib’

def typeof(object)  
System::Type.GetTypeFromHandle(System::Type.GetTypeHandle(object))  
end

We are evaluating IronRuby and/or IronPython to use as event handling  
script language in a WPF / XAML GUI project.

Our current XAML / C# design has the regular VS2008 -generated logic of  
creating custom class (and enbedded BAML) for each XAML-file. We also  
use heavily custom controls to build up larger panels / windows:

MyControl.xaml:

...

Window1.xaml:

 ... ... ... ...

While I have been able to attach event handlers defined in IronPython  
2.0 to the various GUI classes, I would find it more natural if I could  
derive classes in Ruby from the corresponding CLR-classes:

class MyControlRuby \< MyControl

def Clicked(sender, args)  
…  
end

However, I suspect that re-using such classes on the XAML-side would not  
work:

 ... ... ... ...

Can someone confirm or deny my assumption about XAML being  
not-so-DLR-language-friendly here as I suppose?

Might this approach have better changes of success if I would use  
IronPython 1.1 that can supposedly compile Python classes to CLR  
classes?
