I have a C# method with the following signature static class IItemExtensions { static void getLock(this Interop.IItem item, object session, out Interop.ILock lock, out string lockedBy); } I am calling it from IronRuby as follows: lock, locked\_by = IItemExtensions.getLock(@item, @session) @item is a System.\_\_ComObject (IUnknown based, not IDispatch) which implements the Interop.IItem method, and @session is another \_\_ComObject Under 0.9, this worked fine - the two out parameters were assigned to lock and locked\_by Under 0.9.1, The method call succeeds (as far as the COM objects are concerned), but it seems like IronRuby can no longer deal with the out parameters, and the following exception occurs: > > lock, locked\_by = IItemExtensions. getLock(@item, @session) > > System::NotSupportedException: ConvertToArraySplatAction @1 not > > supported on > > foreign meta-objects > > from (irb):30 > > from C:/Dev/TEST/ruby/lib/ruby/1.8/irb.rb:150:in `eval_input' from :0:in`eval’ > > from workspace.rb:80:in `evaluate' from C:/Dev/TEST/ruby/lib/ruby/1.8/irb.rb:147:in`eval\_input’ > > from irb.rb:257:in `signal_status' from C:/Dev/TEST/ruby/lib/ruby/1.8/irb.rb:146:in`eval\_input’ > > from :0:in `loop' from C:/Dev/TEST/ruby/lib/ruby/1.8/irb.rb:70:in`start’ > > from C:/Dev/TEST/ruby/lib/ruby/1.8/irb.rb:69:in `start' from :0:in`catch’ > > from C:/Dev/TEST/ruby/bin/iirb:13 > > from :0:in `catch’ Is there a new way for calling methods with out parameters in 0.9.1 ? ---

Out arguments still work as a returned array, but this looks like a bug as the ConvertToArraySplatAction seems to now work when dealing with a COM object “lock”. I’ll let Tomas field this.

Right. I’ll write a C# helper method which converts the out params into a structure and return that for now. Cheers On Wed, Sep 30, 2009 at 12:16 PM, Jimmy S. \< ---
