c# - How to user where in Set<> Method in Entity Framework -

i have unitofwork interface :

public interface iunitofwork {         //some other methods     idbset<tentity> set<tentity>() tentity : class; } 

and implement this:

public class storecontext : dbcontext, iunitofwork {     public new idbset<tentity> set<tentity>() tentity : class     {             return base.set<tentity>();     } } 

and use set methods service layer :

public class brandservice : ibrandservice {     private readonly iunitofwork _uow;     private readonly idbset<brand> _brands;      public brandservice(iunitofwork uow)     {             _uow = uow;             _brands = _uow.set<brand>();     } } 

i want use in service layer after set method :

_brands = _uow.set<brand>().where(row=>row.isactive == true); 

but returns error :

cannot implicitly convert type 'system.linq.iqueryable' 'system.data.entity.idbset'

how can ?

i searched on google cant find similar question.

i used code :

 _uow = uow;  _brands = _uow.set<brand>();   var data = _uow.set<brand>().where(e => e.isdeleted == false);  _brands = (idbset<brand>)data.tolist(); 

but returns buildplan.cs not found

you can't assign iqueryable idbset. change declaration

private iqueryable<brand> _brands;
