Generic fun

Generics are really cool…

 

…

 

bummer – i thought i might have one of those "You’re our lucky 1,000,000th person who said that winner!" banner descend from Javascript heaven.

 

Anyway I had a hard time using them vs. code-generation of collection classes since code gen had the advantage of non-generic _names_. But I just found out we can do this:

 

 

public sealed class Role

{

    private string _roleName;

    public string RoleName

    {

        get { return _roleName; }

    }

}

 

public sealed class RolesCollection : List<Role>

{

   public Role this[string roleName]

   {

      get

      {

          foreach( Role r in this )

              if( r.RoleName == roleName ) return r;

          return null;

       }

   }

}

 

Now I can have my cake and eat it too. Yum.
