What are the keywords that are used in Constructor() : Keyword

I started learning C#, and I saw that in inheritance we do :

derivedClass(): base()

and then I noticed in another example the use of :

Constructor(): this(parameter)

which I didn't quite understand

my question is do the keywords that are used like this

Constructor() : Keyword

have a name ? and what are some of them, and there uses?

Thank you !

Solution

  • The specification refers to these as constructor-initializers, and lists this and base as valid. From the spec:

    10.11.1 Constructor initializers

    All instance constructors (except those for class object) implicitly include an invocation of another instance constructor immediately before the constructor-body. The constructor to implicitly invoke is determined by the constructor-initializer:

    • An instance constructor initializer of the form base(argument-listopt) causes an instance constructor from the direct base class to be invoked. ...

    • An instance constructor initializer of the form this(argument-listopt) causes an instance constructor from the class itself to be invoked. ...
