This and That

Dear Future Jamie:

DI with a private constructor

When you are doing DI with a private constructor, this syntax will not work:

            String animalTypeName = ConfigurationManager.AppSettings["animalTypeName"].ToString();
            Type animalType = Type.GetType(animalTypeName);
            IAnimal animal = (IAnimal)Activator.CreateInstance(animalType);

Instead use this syntax:

            String animalTypeName = ConfigurationManager.AppSettings["animalTypeName"].ToString();
            Type animalType = Type.GetType(animalTypeName);
            IAnimal animal = (IAnimal)FormatterServices.GetUninitializedObject(animalType);

Params Keyword

When you have a series of overloaded methods that are taking on an ever-growing number of parameters, consider using the params keyword.  For example, instead of this:

        public void NameMe(String FirstName)
        {

        }

        public void NameMe(String FirstName, String LastName)
        {

        }

        public void NameMe(String FirstName, String MiddleName, String LastName)
        {

        }

Do this:

        public void NameMe(params String[] parameters)
        {

        }
