How would you implement inheritance using VB.NET?
When we set out to execute a class using inheritance, we must first begin with an existing class from which we will derive our new subclass. This existing class, or base class, may be part of the .NET system class library framework, it may be part of some other application or .NET assembly, or we may make it as part of our existing application. Once we have a base class, we can then execute one or more subclasses based on that base class. Each of our subclasses will automatically have all of the methods, properties, and events of that base class including the implementation behind each method, property, and event. Our subclass can add new methods, properties, and events of its own - extending the original interface with new functionality. Additionally, a subclass can change the methods and properties of the base class with its own new implementation - effectively overriding the original behavior and replacing it with new behaviors. Essentially inheritance is a way of merging functionality from an existing class into our new subclass. Inheritance also defines rules for how these methods, properties, and events can be merged.
