Question

After quick overview I didn’t find how to deal with linq to sql if I have several nested inner joins.

That’s what I’d like to have in linq

SELECT Booking.BookingId, Booking.EventId, Booking.StartDate, Event.Name, Person.FirstName
FROM Booking
    INNER JOIN Event 
        INNER JOIN Asset
        ON Asset.AssetId = Event.AssetId
        INNER JOIN Person
        ON Person.PersonId = Event.ContactPersonId
    ON Event.EventId = Booking.EventId AND Event.State = 4

Does anyone know how to translate it to LINQ?
Thanks.

Answer 1

var q1= from a in booking,b in event,c in asset, d in person where a.eventid=b.eventid and b.state=4 and c.assetid = b.assetid and b.contactpersonid=d.personid select a,b,c,d

you can replace a,b,c,d at then with the column names you want

another way is to use the join keyword:

var w1= from a in booking join b in event on a.eventid equals b.eventid join c in asset on ...
