混淆linq和IEnumerable或IList

Question

如果GetAddresses（）返回IList，有人可以解释为什么我在'results'语句中得到'没有翻译到sql'错误但是如果它返回IEnumerable则没有？

var addresses= GetAddresses(dataContext);

results = results.Where(r => r.People.Any(a => Addresses.Contains(a)));

Answer 1

你试过了吗？

 results = results.Where(r => r.People.Any(a => Addresses.Contains(a))).ToList();
