i know how can pass query webapi controller? possible, not find examples online further guide me build.

public class testcontroller : apicontroller {      private cdwentities db = new cdwentities();      private query respository;      [httpget]     public httpresponsemessage getdata()     {        // not sure how pass method query class here?              } } 

many help.

first of why method in static?

public static userdetails[] binddatatable() 

so if static must consume this.

var result = query.binddatatable(); 

but if mistake must consume this, current implementation correct, have remove static modifier , call on respository instance.

[httpget] public httpresponsemessage getdata() {    var result = repository.binddatatable(); }
