Hello,

IronRuby throws misleading error message, when I call private method of  
the C# class.

* * *

C#  
public class Cls {  
private void private\_method() {}  
}

Ruby:  
Cls.new.private\_method

Output:  
#\<ArgumentError: wrong number or type of arguments for  
`private\_method’\>

* * *

- Alex.

Could you file a bug @ [http://rubyforge.org/projects/ironruby/](http://rubyforge.org/projects/ironruby/)?

Thanks,
