从集合中选择最大的项目,有些标准
问题描述:
我是新来的.NET 3.5。 我有一个项目的集合:
i am new to .net 3.5. I have a collection of items:
IList<Model> models;
其中
class Model
{
public string Name
{
get;
private set;
}
}
我想获得的元素,它有最长名字的长度。 我试过
I would like to get the element, which has the longest name's length. I tried
string maxItem = models.Max<Model>(model => model.Name.Length);
但它当然返回的最大长度(我需要一个型号
)对象。我知道有使用扩展方法这样做的方式,但我不知道怎么办。
but it of course returns the maximum length (and I need a Model
object). I know there is a way of doing this using the extension methods but I don't know how.
答
这是我怎么得到它的工作。也许有更好的方法,我不知道:
This is how I got it to work. Maybe there's a better way, I'm not sure:
decimal de = d.Max(p => p.Name.Length);
Model a = d.First(p => p.Name.Length == de);
