在C#中,给出以下代码:
public class Person
{
public int PersonID { get; set; }
public int Age { get; set; }
public string Name { get; set; }
}
和
List<Person> people = new List<Person>();
for (int i = 0; i != 15; i++)
{
Person p = new Person();
p.PersonID = i;
p.Age = i * 12;
p.Name = "Name " + i;
people.Add(p);
}
var sortedPeople = from qPeople in people
where qPeople.Age > 0 && qPeople.Age < 25 || qPeople.Age > 100
orderby qPeople.Age descending
select qPeople;
是否可以不带循环将sortedPeople的结果加载回List 中?
谢谢。
最佳答案
是的。有一个.ToList()扩展方法,因此您需要做的就是这样调用它。
var sortedPeople = (from qPeople in people
where qPeople.Age > 0 && qPeople.Age < 25 || qPeople.Age > 100
orderby qPeople.Age descending
select qPeople).ToList();
现在sortedPeople将是
List<Person>
而不是IOrderedEnumerable<Person>
