The override modifier can be used on virtual methods, but it must be used on abstract methods. This instructs the compiler to implement it using the last defined method. Even if the method is called on a reference to the base class, it will use an implementation that overrides it.
The new modifier instructs the compiler to use the child implementation instead of the parent implementation.Any code that does not reference your class but references the parent class will be implemented using the parent class。

Declare two classes: BaseClass and DerivedClass. DerivedClass inherits from BaseClass. As shown below:



Code:


In simple terms: when the parent class refers to a child class object, the method is called if it is override, the subclass method is executed; If you use new override, you are executing the parent class's method.
