在Entity Framework中获取相对表的前m个记录的前n个记录

Question

I have a table Categories and Products . One category can have multiple products and I want to get TOP 5 products and TOP 3 categories for each product. I tried

entity.Categories.Include("Products").Take(3)

But output of this is 3 Categories and all products under them. I tried

entity.Categories.Take(5).Include("Products").Take(3)

But of course it won't work because Include can't be called in Take . So what could be the solution? Please suggest.

Answer 1

Finally I have solved it

var result = entity.Categories.Select
                         (
                            cats => new
                                {   
                                    cats.CategoryName,
                                    cats.Description,
                                    Products = cats.Products.Take(3)
                                }
                         ).Take(5);
