Linq relational table include

Question

I have 4 relational table;

1. Category
2. Product
3. ProductBrand
4. ProductImage

I need linq query included 3 table

Answer 1

Use Include

from b in db.ProductBrands.Include("Products.ProductImages") 
where b.CategoryId == 5
select b;

Or the extension method Include.

Answer 2

Instead of just select b, write like this select b.col1, i.col1, b.coln, i.coln....;

The above will always return anonymous type object instead of a specific class...

Thanks
