What is the syntax for an inner join in LINQ to SQL?

Question

I\'m writing a LINQ to SQL statement, and I\'m after the standard syntax for a normal inner join with an ON clause in C#.

How do you represent the follo

Answer 1

basically LINQ join operator provides no benefit for SQL. I.e. the following query

var r = from dealer in db.Dealers
   from contact in db.DealerContact
   where dealer.DealerID == contact.DealerID
   select dealerContact;

will result in INNER JOIN in SQL

join is useful for IEnumerable<> because it is more efficient:

from contact in db.DealerContact  

clause would be re-executed for every dealer But for IQueryable<> it is not the case. Also join is less flexible.
