c# - 检查我的对象是否在 C# 中实现通用接口(interface)

Question

我有那个界面:

public interface IEntityWithTypedId<T>{}

并且有两个类:

public abstract class EntityWithTypedId<TId> : IEntityWithTypedId<TId>{...}
public abstract class Entity : EntityWithTypedId<int>{...}    

所以我有这样的实体:

public class TestA : Entity
public class TestB : EntityWithTypedId<string>
public class TestC : EntityWithTypedId<byte>

如何检查我的实体是否实现了 IEntityWithTypedId ？

谢谢

Answer 1

typeof(TestA).GetInterfaces()
    .Any(i => i.GetGenericTypeDefinition() == typeof(IEntityWithTypedId<>))
