Question

I have: - an interface : IMyType - some classes implementing it : MyType1 , MyType2 , MyType3

How can I define a list of type IMyType?

var myList = new List<Type> {typeof (MyType1), typeof (MyType2)};

以上清单并不强迫类型为IMyType,我可以在名单上添加任何类型。

Answer 1

class Program
{
    static void Main(string[] args)
    {
        IList<IMyType> lst = new List<IMyType>();
        lst.Add(new MyType1());
        lst.Add(new MyType2());
        lst.Add(new MyType3());

        foreach (var lstItem in lst)
        {
            Console.WriteLine(lstItem.GetType());
        }
    }
}
public interface IMyType { }
public class MyType1 : IMyType { }
public class MyType2 : IMyType { }
public class MyType3 : IMyType { }

If you want determine what s implementation class, you can use obj.GetType() or operator obj is MyType1

Answer 2

简单

List<IMyType> list = new List<IMyType>();

你们不需要任何ancy子。
