In C#, the : base(true) syntax appears within a constructor definition. Let’s break it down:
1. Base Class Constructor Chaining:
- The : base(...) syntax allows a derived class (a class that inherits from another class) to chain to a constructor in its base class (parent class).
- When you create an instance of a derived class, its constructor can call a constructor in the base class before executing its own code.
- This is useful for initializing common properties or performing shared setup logic.
2. : base(true) Specifically:
- The : base(true) part indicates that the derived class constructor should invoke a constructor in the base class that accepts a single argument of type bool.
- The value true is passed as an argument to the base class constructor.
In this example, the Child class’s constructor calls the base class constructor with the true argument.
The base class constructor with the bool parameter will be executed before any code inside the Child class constructor.
Remember that the : base(...) syntax allows you to explicitly choose which base class constructor to call,
ensuring proper initialization and avoiding ambiguity when multiple constructors exist in the base class.
