In the query below, I want to return people that meet multiple conditions. Some of the conditions apply to fields in the table containing the people to be returned. The other condition is applied to a different table (EmailAddresses) linked to the main table (People) via PersonId.

var t = People.Where(x =>
            x.Type == 102 &&
            x.FirstName == "Bob" &&
            x.LastName == "Williams" &&
                 x.EmailAddresses.Where (ea=> ea.EmailAddress
                                                 == "bob.williams@acme.org")
            )
            .Select(x => x.PersonId)

How do I do this?

    Do understand this right, at least one of them should have that adress? If yes, use the Any method:

    var t = People.Where(x =>
            x.Type == 102 &&
            x.FirstName == "Bob" &&
            x.LastName == "Williams" &&
                 x.EmailAddresses.Any(ea=> ea.EmailAddress
                                                 == "bob.williams@acme.org")
            )
            .Select(x => x.PersonId)

    Any returns true if at least one of the elements of the IQueryable<T> fulfills the predicate.
