c# - Call Interface Method from Console Application -

i have web application have class:

public class ptpostalcodeservice : iptpostalcodeservice {     private readonly irepository<ptpostalcode> _ptpostalcoderepository;     public ptpostalcodeservice(irepository<ptpostalcode> ptpostalcoderepository)     {         _ptpostalcoderepository = ptpostalcoderepository;     }     public ptpostalcodedto getptpostalcode(int postalcode, int? postalcodeextension)     {         ptpostalcode ptpostalcodedomain = new ptpostalcode();          ptpostalcodedomain = _ptpostalcoderepository.get(             filter: p => p.postalcode == postalcode && (postalcodeextension.hasvalue == false || p.postalcodeextension == postalcodeextension),             includeproperties: "ptcouncil, ptcouncil.ptdistrict").firstordefault();          var ptpostalcodedto = mapper.map<ptpostalcode, ptpostalcodedto>(ptpostalcodedomain);          return ptpostalcodedto;     } } 

now need access methid getptpostalcode consoleapplication, idea?

edit:

i have autofac manage constructors:

// repository builder.registergeneric(typeof(repository<>))             .as(typeof(irepository<>))             .instanceperhttprequest(); 

the interface of repository:

public interface irepository<t> t : class 

thanks.
