Question

I have a enum:

[Flags]
public enum EmailType
{
    PasswordRecovery = 1,
    Activation = 2,
    SendTicket = 4
}

For example, in a table we have value equals 3 that means – PasswordRecovery, Activation.
This is my query:

var emailType = EmailType.PasswordRecovery;
return Database.EmailSettings.FirstOrDefault(es => es.EmailType ==  (int)emailType);

Of course this query not works properly:3 == 1 => false.
How to filter properly?
Thanks.

UPDATE:
I’m using Flags attribute because there is one more application written with XAF (devexpress framework) and I have one feature in UI that required Flags attribute.

Answer 1

int emailType = (int)EmailType.PasswordRecovery;
return Database.EmailSettings.FirstOrDefault(es => (es.EmailType & emailType) == emailType);

Edit: I added a cast since es.EmailType is and int.
