I'm using the LINQ Driver for C#, works great.

Sorting a lot of properties but heres a problem I can't solve, its probebly simple.

var identifierList = new []{"10", "20", "30"};
var newList = list.Where(x => identifierList.Contains(x.Identifier));

This is NOT supported ... 

So I could do something like:

 var newList = list.Where(x => x.Identifier == "10" || x.Identifier == "20" || x.Identifier == "30");

But since the list is variable ... how do I construct the above? Or are there even better alternatives?

The list is of type IQueryable<MyCustomClass>

For information ... this is used as a filter of alot of properties. In SQL I could have a parent -> child relationship. But as I can't as the parent for the main ID I need to take all the ID's out and then construct it like this.

Hopes this makes sense. If needed I will explain more.
