Is it possible to add a list into another list whilst changing class type from Deal to DealBookmarkWrapper without using the foreach statement?

var list = new List<IBookmarkWrapper>();
foreach (var deal in deals)
{
    list.Add(new DealBookmarkWrapper(deal));
}

Thanks.

If you want the exact equivalent:

var list = deals.Select(d => new DealBookmarkWrapper(d))
                .Cast<IBookmarkWrapper>()
                .ToList();

But if you’re just iterating over the elements and don’t really need a List, you can leave off the call to GetList().
