What is the purpose of the new keyword as a modifier in C#?

The purpose of the new keyword in C# as a modifier is to indicate that a member in a derived class is intentionally hiding a member of the same name in the base class. When you use the new keyword, you signal that the derived class member is distinct and will replace the base class implementation when accessed through a reference of the derived class type. This allows the derived class to provide a new implementation or behavior, while still maintaining the existence of the original member in the base class.

Using the new modifier is particularly useful in scenarios where the derived class's functionality is different from the base class's implementation, but you still want to use the same member name for clarity or compatibility in the interface. This technique is often referred to as member hiding, and it's important for developers to comprehend that the original member remains accessible when using a reference to the base class.

In summary, the new keyword serves a distinct purpose in C# by allowing for the intentional hiding of inherited members, providing clarity and control over member accessibility and behavior within an inheritance hierarchy.
