Question

发生了参照完整性约束违规：属性定义引用约束的值不一致在关系中的主要和依赖对象之间。

我在没有延迟加载的情况下使用EF6。当我附加一个修改了外键属性的对象而不归零其导航属性时，通常会发生此错误。

但是现在我有一个关系如此多的对象，所以，有一种方法可以获得导致错误的确切属性吗？

异常详情：

  Message=A referential integrity constraint violation occurred: The property values that define the referential constraints are not consistent between principal and dependent objects in the relationship.
