如何在LINQ中使用GroupBy？

Question

在listProducts我有一个名为“家庭”的字段。我想GroupBy这个领域。

var products = from listProducts in repository.All() 
               where (listProducts.Code == "48654")
               select listProducts;`

Answer 1

试试这个，

var products = from listProducts in repository.All()
                where listProducts.Code == "48654"
                group listProducts by listProducts.family into grp
                select grp;
