join

I have this linq query:

var segreterie = from s in db.USR_Utenti join h in db.USR_Accounts
                     on new {s.ID, settings.GruppoSegreteria} 
                     equals new {h.USR_UtentiReference,h.ID_Gruppo} select s;

that has this problem:

The type of one of the expressions in the join clause is incorrect.  Type inference failed in the call to 'Join'.

how can i do to solve it?

Dynamic Type to do away with Reflection

as seen on West-Wind - Search for 'West-Wind'
The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
