我如何将其转换为lambda表达式？

Question

wondering if anyone can help. This works, but I was wondering how it would look in Lambda instead (Just curious !)

Codes is simply an array of id's and each item has a code...

        var qry = from i in items
                where Codes.Contains(i.Code)
                select i;

        return qry.ToList();

Thanks Andrew.

Answer 1

return items.Where(i => Codes.Contains(i.Code)).ToList();

Answer 2

var qry = items.Where(i => Codes.Contains(i.Code));

Answer 3

如果items是List<Item> ，则可以这样保存自己的ToList()调用：

var qry = items.FindAll(i => Codes.Contains(i.Code));
