#648 – Using an Object Initializer

You typically initialize the data members of an object by invoking one of the object’s constructors and passing it any information that it requires.  For example:

Dog kirby = new Dog("Kirby", 14);

If a parameterless constructor exists for the class, you can alternatively create the object without invoking a constructor, using the object initializer syntax shown below.

Dog kirby = new Dog { Name="Kirby", Age=14 };

This is functionally equivalent to:

Dog kirby = new Dog();
kirby.Name = "Kirby";
kirby.Age = 14;

If a parameterless constructor does not exist for the class, you can still use the object initializer syntax, but only after explicitly invoking one of the constructors.
