Multi-level inheritance simply means that a class can inherit from another class which itself inherits from a third class and so on for as many levels as you like. So in this example: class A { } class B : A { } class C: B { } C inherits from B which itself inherits from A. This is therefore an example of 3 level inheritance. In fact to be strictly accurate it is an example of 4 level inheritance because A inherits 'implicitly' from the System.Object class which sits at the top of the .NET type hierarchy. You could prevent further inheritance from taking place by making C a 'sealed' class. Note that multi-level inheritance is not the same as multiple inheritance. The latter occurs when a class inherits from two or more parent classes. This isn't allowed in .NET which only supports single inheritance i.e. a class can inherit from (at most) one parent.
