Can this Linq query be entered as nothing but "var"?

Question

When I make a request that returns an anonymous type

    var assets =
        from Product p in Session.CreateLinq<Product>()
        where bundles.Contains(p.ProductBundle)
        select new {p.Asset, p.Asset.PropertyTbl};

Can I print a return to anything other than var?

Answer 1

You cannot * return an anonymous type, because the caller does not know which type it cannot use.

If you want to return the results, you can create objects of a non-anonymous type:

IEnumerable<Foo> assets =
    from Product p in Session.CreateLinq<Product>()
    where bundles.Contains(p.ProductBundle)
    select new Foo { Bar = p.Asset, Baz = p.Asset.PropertyTbl};

You can also use the Tuple type in .NET 4 if you do not want to create your own class for your values.
