Question

你好，我有一个名为Animal.cs的课程，在我的Program.cs中，我创造了一些动物......

class Program
    {
        static void Main(string[] args)
        {
            var AnimalList = new AnimslList();
        animalList.Add(new Animal{ Active = true, Name = "Bob", Photo = "Espanha" });
        animalList.Add(new Animal { Active = false, Name = "Robby", Photo = "Portugal" });
        animalList.Add(new Animal { Active = true, Name = "Snoop", Photo = "UK" });
        }
     }

我有一个类AnimalList.cs，在那个类我添加了动物列表，我用这个代码获取活动动物：

class AnimalList : List<Animal>
{
    public List<Animal> GetActiveAnimals()
    {
        return this.FindAll(p => p.Active);
    }
}

我的问题是在这个课程中他在event.cs中调用了Event.cs我希望得到GetActiveAnimals（）的结果，因为我只想得到活动的活跃动物，有人可以帮助我吗？

class Event
    {
        private AnimalList _contestants;
    }

我应该从上面这一个中的AnimaList获得Active。活跃的应该进入_contestants

Answer 1

通过构造函数扩展您的事件，例如

class Event
{
    private AnimalList _contestants;
    public Event(AnimalList contestants)
    { 
         _contestants = contestants;
    }
}

然后在创建活动时转发列表：

static void Main(string[] args)
{
    var AnimalList = new AnimslList();
    animalList.Add(new Animal{ Active = true, Name = "Bob", Photo = "Espanha" });
    animalList.Add(new Animal { Active = false, Name = "Robby", Photo = "Portugal" });
    animalList.Add(new Animal { Active = true, Name = "Snoop", Photo = "UK" });
    var event = new Event(AnimalList.GetActiveAnimals();
}

C＃从列表中保存
