首先，对不起，我的英语很差。我正在使用MassTransit和Azure服务总线进行微服务之间的异步通信。
由于项目设计要求，在masstrait中发送和/或发布的对象是实现接口并具有继承性的对象(类实例(，这意味着；消息类型"属性是多个值的数组，这导致发送/发布"；副本"；对象的每个基类和接口的对象的。
由于应用程序实际上只需要处理最后一个类，因此这种行为的结果是创建了从未处理过的队列和消息类型的主题。
是否有方法修改MessageType数组以删除所有不必要的项？
示例：
这是一条最新消息：

简短回答：无
MassTransit将反映所有支持的类型，并将它们包含在消息信封中，以支持多态消息传递和反序列化。
您可以排除在消息代理上创建为交换/主题的消息类型，但这不会在序列化期间将它们从消息类型数组中排除。
