What is the return type of my linq query?

Question

I have two tables A & B. I can fire Linq queries & get required data for individual tables. As i know what each of the tables will return as shown in example. But,

Answer 1

The value you generate is called Anonymous Type and you can return it unless you return object like:

private object GetJoinAAndB()
{
    var query = from a in objA
                join b in objB
                on a.ID equals b.AID
                select new { a.ID, a.Name, b.Address };
    return query.ToList();
}

There are two good solutions:
1. is to generate a class to match the output and generate it like Kobi solution
2. if you are using .net 4 you can return a dynamic type like

private dynamic GetJoinAAndB()
{
    var query = from a in objA
                join b in objB
                on a.ID equals b.AID
                select new { a.ID, a.Name, b.Address };
    return query.ToList();
}

then you can use it later. You can search the internet about the advantage of using dynamic keyword.
