Interface blues

[seanwright]

Ok, I got a piece of code and I can't seem to compile it... I don't quite know how to ask the question so here goes. I have the following code: public interface X : _Collection { [DispId(0)] Y this[object ] { get; set; } } Where Y is another interface. I get an 'Identifier expected' message when I compile. Can anyone explain this code and a possible solution? Thanks!

You have forgotten to give the argument in the indexer a name. Y this[object _index_]
