How do I get the max ID with Linq to Entity?

Question

c# entity-framework linq linq-to-entities

I have a table User which has an identity column UserID, now what is the correct Linq to Entity line of code that would return me the max UserID?

I've tried:

using (MyDBEntities db = new MyDBEntities())
{
    var User = db.Users.Last();
    // or
    var User = db.Users.Max();

    return user.UserID;
}

but Last and Max don't seem to be supported.

Any ideas?

try this

int intIdt = db.Users.Max(u => u.UserId);

Update:

If no record then generate exception using above code try this

int? intIdt = db.Users.Max(u => (int?)u.UserId);

Do that like this

db.Users.OrderByDescending(u => u.UserId).FirstOrDefault();
