接口中的隐式泛型类型

Question

我有一个界面：

public interface ILabel <A, F> where A: IAddress where F: IFeatures
{
    A Sender { get; set; }

    A Receiver { get; set; }

    F Features { get; set; }
}

还有一个 class 继承自这个接口：

public class Label : ILabel<Address, Features>
{
    public int LabelId { get; set; }

    [Required]
    public Address Sender { get; set; }

    [Required]
    public Address Receiver { get; set; }

    [Required]
    public Features Features { get; set; }

    public string Identcode { get; set; }

    public string Base64 { get; set; }
}

我想通过 ILabel 初始化 Label object 而不在 ILabel 提供泛型类型，如下所示：

ILabel label = new Label();

我知道这在 Java 中是可能的。 你知道如何实现吗？ 提前致谢！

Answer 1

我找到了解决方案：

标签：

public interface ILabel
{
    IAddress Sender { get; set; }

    IAddress Receiver { get; set; }

    IFeatures Features { get; set; }
}

额外的新 class 用作抽象基础 class，如桥

public abstract class BaseLabel<A, F> : ILabel where A: IAddress where F: IFeatures
{
    public virtual A Sender { get; set; }

    public virtual A Receiver { get; set; }

    public virtual F Features { get; set; }

    IAddress ILabel.Sender
    {
        get
        {
            return Sender;
        }
        set
        {
            Sender = (A)value;
        }
    }

    IAddress ILabel.Receiver
    {
        get
        {
            return Receiver;
        }
        set
        {
            Receiver = (A)value;
        }
    }

    IFeatures ILabel.Features
    {
        get
        {
            return Features;
        }
        set
        {
            Features = (F)value;
        }
    }
}

和 Label class

public class Label : BaseLabel<Address, Features>
{
    public int LabelId { get; set; }

    public string Identcode { get; set; }

    public string Base64 { get; set; }
}
