c# - Performing Linq operation on multiple possible combination of nullable values -


the title , method explains every thing. need perform search on bases of multiple options. don't want write possible conditions. suggestions?

public list<ticket> gettickets(status? status,priority? priority,ticketlevel? ticketlevel,         datetime? createdon,datetime? modifiedon,bool? removed)     {         if(status!=null && priority !=null && ticketlevel!=null && createdon==null && modifiedon==null && removed ==null)         {             using (crmcontext context=new crmcontext())             {                 return context.tickets.where(                     t => t.status == status && t.priority == priority && t.ticketlevel == ticketlevel).tolist();             }         }         throw new notimplementedexception();     }

thank you!

you use solution dave bish, or use ternary operator here.

return context.tickets.where(t =>                 (status != null ? t.status == status : true) &&                 (priority != null ? t.priority == priority : true) &&                 (ticketlevel != null ? t.ticketlevel == ticketlevel : true)).tolist();

there obvious advantages either. solution dave provided has advantage of readability/maintenance. downfall is chaining, , therefore can only and (&&) condition.

the solution here has ability can change && operators || well. downfall readability/ease of maintenance.

personally, whichever choose you.
