c# - How to get all Products within a Category or sub-category -

i'm trying products within 1 category, want search categoryid. want list filled products categoryid example 3.

how can this, i'm using nopcommerce 3.10.

someone on nop forum achieved using following line:

_productservice.searchproductvariants(categoryid, 0, string.empty, false, 0, int.maxvalue, false); 

but since use 3.10 , productvariants replaced products, can't use this.

thanks in advance!

i figured out myself:

for products within 1 categoryid:

        nopengine _engine;         /// <summary>         /// returns ipagedlist(product) filled products selected categoryid         /// </summary>         /// <param name="categoryid"></param>         /// <returns></returns>         public ipagedlist<product> getallproductsfromcategory(int categoryid)         {             _engine = new nopengine();             var _productservice = _engine.resolve<iproductservice>();             list<int> categoryids = new list<int>();             categoryids.add(categoryid);             return _productservice.searchproducts(categoryids: categoryids);         } 

for products:

        nopengine _engine;         /// <summary>         /// returns ipagedlist(product) filled products, without selection         /// </summary>         /// <returns></returns>         public ipagedlist<product> getallproducts()         {             _engine = new nopengine();             var _allservice = _engine.resolve<iproductservice>();             return _allservice.searchproducts();         }
