Ironruby core - Jun 2010 - RubyArray to List<T> ?

Hello,

I have a block of code which returns me a RubyArray back into C# code.
While I can get access to the strongly typed objects inside using
reflection, I was wondering if there was any way to get the data back
as a List<T> ?

Example of the code at the moment:
            RubyArray o = (RubyArray) filters[1].GetFilteredOutTweets(tweets);
            Console.WriteLine(o);
            Console.WriteLine((o[0] as Tweet).User);


GetFilteredOutTweets returns an object as when it returned List<Tweet>
it was causing it to fail.

Make sense?

Thanks

Ben

RubyArray is IList<object>, its items might be of arbitrary (different)
types.

You can certainly try to cast all of them to a single type:
            var list = new List<Tweet>(array.Count);
            foreach (Tweet item in array) {
                list.Add(item);
            }

Tomas

var list = array.Cast<Tweet>(); would be cleaner.
