在C#中订阅接口的事件

public interface IEventInterface
{
    event EventHandler MyEvent;
}

public class EventClass : IEventInterface
{
    public event EventHandler MyEvent;

    public void RaiseEvent()
    {
        MyEvent?.Invoke(this, EventArgs.Empty);
    }
}

public class EventSubscriber
{
    public void Subscribe(IEventInterface eventObject)
    {
        eventObject.MyEvent += HandleEvent;
    }

    private void HandleEvent(object sender, EventArgs e)
    {
        // 处理事件的逻辑
    }
}

EventClass eventObject = new EventClass();
EventSubscriber subscriber = new EventSubscriber();
subscriber.Subscribe(eventObject);

eventObject.RaiseEvent();
