everything ok... cannot access getmemberid() method.. pls tell me how can access getmemberid() controller...

regard, minthittun

modify iregistration interface adding int getmemberid(string username, string pwd) method:

public interface iregistration<t> {     bool registration(t entity);     int getmemberid(string username, string pwd); } 

after all, thing should read interfaces (c# programming guide)

update:

public interface imembersrepository {     int getmemberid(string username, string password);     // other stuff related members... }  public class membersrepository : imembersrepository {     private smileworkdbentities db = new smileworkdbentities();      public int getmemberid(string username, string password)     {         var mem = (from m in db.members m.member_username == username && m.member_password == pwd select m).firstordefault();         return mem.member_id;     }     // other stuff related members... }  public class membersregistrationcontroller : controller {     iregistration<member> ireg1;             imembersrepository membersrepository;      public membersregistrationcontroller(iregistration<member> _ireg1, imembersrepository memrepository)     {         ireg1 = _ireg1;                     membersrepository = memrepository;     }      // ... }
