Castle ActiveRecord DeleteAll on belongsto restraint

我有两个类，设置如下:

[ActiveRecord("ReceivedMessage")]
class ARReceivedMessage : ARBase<ARReceivedMessage>

:

[ActiveRecord("ReceivedMessageReply")]
class ARReceivedMessageReply : ARBase<ARReceivedMessageReply>
[BelongsTo(Type = typeof(ARReceivedMessage), Column = "ReceivedMessageID")]
public ARReceivedMessage Message { get; set; }

当尝试清理数据库时，我首先要删除所有的ReceivedMessageReply对象，然后再删除ReceivedMessage本身。在代码中，这给我带来了以下内容:

获取我想要删除的所有receivedMessages:

ARReceivedMessage[] messagesToDelete = ARReceivedMessage.GetAll(messageCriterion);

获取删除所有ReceivedMessageReplys的条件并删除它们:

ICriterion relatedCriterion = Restrictions.In("ReceivedMessageID", messagesToDelete);
ARReceivedMessageReply.DeleteAll(relatedCriterion);

activerecord告诉我以下内容:无法解析属性:ReceivedMessageID: ARReceivedMessageReply

你知道我哪里出错了吗?

Thanks in advance

ICriterion relatedCriterion = Restrictions.In("Message", messagesToDelete);
