c# - Implement Interface and accessing methods -

public partial class shoppingcart : isecurisable {     public void deactivate()      {         shoppingcartid = null;         isactive = false;         foreach (var shoppingcartdetails in childs)         {             shoppingcartdetails.parentid = parentid;         }     } } 

how can access deactivate() method after i've implemented isecurisable on class.

you can use form

isecurisable shoppingcart = new shoppingcart(); shoppingcart.deactivate();  public interface isecurisable {     void deactivate(); }  public partial class shoppingcart : isecurisable {      public void deactivate()      {          shoppingcartid = null;          isactive = false;          foreach (var shoppingcartdetails in childs)          {             shoppingcartdetails.parentid = parentid;          }      } }
