LINQ到SQL嵌套的內部連接？

快速瀏覽後，我沒有找到如何處理LINQ到SQL，如果我有幾個嵌套的內部聯接。LINQ到SQL嵌套的內部連接？

這就是想什麼我有在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

有誰知道如何把它翻譯成LINQ？謝謝。

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

你可以再更換A，B，C，d與要

列名的另一種方式是使用join關鍵字：

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

謝謝，也想出瞭如何做到這一點，並採用了你在第二個例子中提出的方法。 – Maxim 2010-11-26 21:58:02

var query = from b in context.Bookings 
    from e in context.Events 
    join a in context.Assets on e.AssetId equals a.AssetId 
    join p in context.People on e.ContactPersonId equals p.PersonId 
    where e.State == (byte)States.Approved && e.EventId == b.EventId 
    select new { EventName = e.Name, BookingDate = b.StartDate };
