Entity Framework Core - Complex list?

Question

I have 3 tables as follows:

Users
Claims
UserClaims

I created the relationship between a user and his claims with the following code:

public class User
{
    public int Id { get; set; }

    [Required]
    public string Name { get; set; }

    public ICollection<UserClaim> UserClaims { get; set; }        
}

I would like to return an array of the Claims that a user has as well. Rather than just a list of their "subscriptions" to said claims.

How can I create a list of Claims (not UserClaims) for the user object. This way I can use User.Claims rather than user.UserClaims (which I know I will need for modifying, but not for basic claim testing).

Answer 1

Typing this on a tablet, so untested code, but you will need to use SelectMany for this. Something like...

jim.SelectMany(u => u.UserClaims.Select(uc => uc.Claim));

As I said, you'll need to check the exact syntax, but that should be close enough to get you going.
