?: Operator in LINQ Query

Question

• How do I utilize a ?: operator in the SELECT clause of a LINQ query? If this can\'t be done, how can I emulate one? The goal is to get a CASE block in my select claus

Answer 1

I'm fairly new to Linq to SQL but I'm pretty sure it would go like this:

var query =
    from a in db.tblActivities
    from i in a.tblIPs
    from u in i.tblUsers 
    select new
    {
        userName = (u.UserName == null)
            ? i.Address
            : u.UserName,
        a.Request,
        a.DateTime
    };

The if statement needs to be in parentheses and the results outside of them. As for the joins, you follow the chain down from one->many.
