Overriding indexers

Ruby IronRuby

Hi
How do I override an indexer on a C# class?

public class IndexerContained{

    private Dictionary<string, string> _inner = new

Dictionary<string,
string>{
{ “key1”, “value1” },
{ “key2”, “value2” },
{ “key3”, “value3” },
{ “key4”, “value4” }
};

    public virtual string this[string name]{
      get { return _inner[name]; }
      set { _inner[name] = value; }
    }
}

I would like to override that indexer with something like

class IndexerContainedMock

def
5
end

def []=(*args)
# nothing here
end
end

Am I doing it wrong or is that not implemented yet?

Pretty sure this isn’t implemented yet, as you can accomplish the same
type of effect with method_missing:

_inner.key2 = “value2”

It definitely should be fixed, but not sure if anyone has it in their
sights. So open a bug =)
