如何通过带有接口的子类的委托使用事件处理程序

public interface IEventHandler
{
    void HandleEvent(object sender, EventArgs e);
}

public class EventHandler : IEventHandler
{
    public void HandleEvent(object sender, EventArgs e)
    {
        // 处理事件的逻辑代码
    }
}

public class EventPublisher
{
    public event EventHandler Event;

    public void PublishEvent()
    {
        // 触发事件
        Event?.Invoke(this, EventArgs.Empty);
    }
}

public class EventSubscriber
{
    private EventPublisher _publisher;

    public EventSubscriber(EventPublisher publisher)
    {
        _publisher = publisher;
        _publisher.Event += new EventHandler(new EventHandler().HandleEvent);
    }
}
