There are two types of inheritance used in modern programming languages. C# and other .NET languages use single inheritance. This means that a subclass may only inherit functionality from a single base class.

Multiple inheritance permits a subclass to have two or more superclasses. In this situation the derived class inherits functionality from several base classes. Multiple inheritance is not supported by C# or the .NET framework. However, this does not stop a class from providing many public interfaces as will be seen in a later article.
