如果我有这两个项目：

MyCompany.ERP.Billing
MyCompany.ERP.Financial

结算问/将信息发送到金融，反之亦然。两者都太大了，所以我不想把它们放在一个单一的项目。 Visual Studio中不允许循环引用。你会如何​​处理呢？

Billing asks/sends information to Financial and vice-versa. Both are too big so I don't want to put them in a single project. Visual Studio doesn't allow circular references. How would you deal with that?

推荐答案

从你的类中提取接口，并把它们放到两个结算从引用的一个核心项目，金融项目。然后，您可以使用这些接口组件之间共享数据。

Extract interfaces from your classes and put them into a core project referenced from both Billing and Financial projects. You can then use those interfaces to share data between assemblies.

这不仅可以让你的通过 2的那些组件之间的对象，但不能创建从其他对象，因为你实际上并没有一个参考的开始。如果您希望能够创建你需要一个工厂，外部对这些2个项目的对象，处理对象的创建。

This only allows you to pass objects between those 2 assemblies, but you can't create objects from the other since you don't actually have a reference to begin with. If you want to be able to create objects you need a factory, external to those 2 projects, that handles object creation.

我会抽取需要共享数据来回结算和金融之间到另一个业务逻辑项目。这将使事情变得更简单，并会为您节省诉诸于所有种类的技巧，使维护的噩梦。

I would extract the business logic that needs to share the data back and forth between Billing and Financial into another project. This would make things a lot easier and would save you from resorting to all sort of tricks that make maintainability a nightmare.
