Generic object in Typescript

Question

I created a Dictionary<TValue> on TypeScript, but it doesn't works like I want, unless that I use it like an array instead of object. It's my Dictionary class:

class Dictionary<TValue> {
    [index: string]: TValue;
}

So I can only use it like this:

var instanceOfDictionary: Dictionary<string> = ...;
console.log(instanceOfDictionary["test"]);

But I would like use like:

console.log(instanceOfDictionary.test);

Is it possible?

Not unless you explicitly add test as a member. So, no.

Really, I think that if I turn it in a class that allow this member will better for me, are limited number of member (about 10), so I think that it'll be better than I use "undefined" members. Thanks.
