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 ?

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  
it was causing it to fail.

Make sense?

Thanks

Ben

RubyArray is IList, 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(array.Count);  
foreach (Tweet item in array) {  
list.Add(item);  
}

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