假设我有一个班级:
public class Item
{
...
public IEnumerable<int> ClientsIds { get; set; }
}
以下代码:
List<Item> items = GetItems();
int[] ids = GetIds();
现在我只需要选择包含ids int数组中任何元素的项目。我该怎么办?
答案 0 :(得分:0)
一个简单的var filteredItems = items.Where(item =>
item.ClientIds.Any(ids.Contains)).ToList();
应该这样做:
public static IEnumerable<Item> FilterItems(this IEnumerable<Item> source, IEnumerable<int> filter)
{
return source.Where(item => item.ClientIds.Any(filter.Contains));
}
我不认为这里需要扩展方法,但你当然可以封装它:
Offending DSA key in ~/.ssh/known_hosts:5
remove with:
ssh-keygen -f "~/.ssh/known_hosts" -R [localhost]:8101
DSA host key for [localhost]:8101 has changed and you have requested strict checking.
Host key verification failed.
