For a project I'm working with Entity Framework and I'd like to be able to enumerate all navigational properties for a given object instance (assuming it's an object generated by EF). From there I'd like to get the related Id property for every navigational property.
For example, if I get an instance of the class Person
, I want to be able to find it's navigational properties called Address
and Boss
. For those two navigational properties I want to then "lookup" the related Id properties called AddressId
and BossId
.
I need those Id properties so I can run queries on a different database which does not have the same foreign keys but does have exactly the same Ids.
So far I have figured out a way to get the RelationshipManager for a random object instance generated by EF. And while debugging I can get to the foreign key relations via the Manager's Relationships
property. But I can only get as far as the navigational property name. So I can see there's a FK_Person_Address
which is related to the navigational property called Address
but I can't find the AddressId
.
So my question is, how can I dynamically (with no knowledge of the Person
class' layout) discover the AddressId
property which is related to Address
?
I am aware the Foreign Key relationship might have the Id property on the other side of the relation (Boss
pointing to Person
in stead of Person
having a BossId
). In that case, I'd still like to discover that Boss
has a PersonId
when I'm inspecting an instance of Person
.
