Question

I have an entity named Affaire as below:

    [Key]
    public string IdAffaire { get; set; }
    public string Title { get; set; }
    public string Note { get; set; }

I also have an entity named Suite as below:

    [Key]
    public string IdSuite { get; set; }
    public string IdAffaire { get; set; }
    public string Description { get; set; }

    [ForeignKey("IdAffaire")]
    public virtual Affaire Affaire { get; set; }

One affaire can have multiple suites.
Each suite is related to one affaire.

In my suite table, I have the following records:

IdSuite/IdAffaire/Description
0001/12.345/Description1
0001/13.666/DescriptionA
0002/13.666/DescriptionB
0003/13.666/DescriptionC
0004/13.666/DescriptionD

The problem: in my code, if I try to get a list of all suites, I get the following:

IEnumerable<Suite> suites

0001/12.345/Description1
0001/12.345/DescriptionA
0002/13.666/DescriptionB
0003/13.666/DescriptionC
0004/13.666/DescriptionD

As you can see, something’s wrong with the data returned??

Do you have an idea?

Thank you very much 🙂

Edited for posting code:

... 
IEnumerable<Suite> suites;
...

When I debug this line of code and inspect the suites variable, I received wrong result (as showed up).

Maybe the problem is that I need to define correctly my primary key on table Suite: composed of two fields IdAffaire an IdSuite How can I do?

Answer 1

Ok, I found the problem: because I have a composite primary key, I need to define it like this:

Suite entity:

[Key, Column(Order=0)]
public string IdSuite { get; set; }
[Key, Column(Order=1)]
public string IdAffaire { get; set; }
public string Description { get; set; }

[ForeignKey("IdAffaire")]
public virtual Affaire Affaire { get; set; }

Thank you anyway 🙂
