Types of Inheritance in c#

Single Inheritance - Derived class is created from a single base class. SUPPORTED

Multi-level inheritance - Derived class is created from another derived class. SUPPORTED

Multiple inheritance - A derived class is created from more than one base class. NOT SUPPORTED

Multipath inheritance - In this inheritance, a derived class is created from multiple derived classes and each of these derived classes have same base class. NOT SUPPORTED

Hierarchial inheritance - In this inheritance, more than one derived classes are created from a single base. SUPPORTED

Hybrid inheritance - This is combination of more than one inheritance. So depending on type of combination we can say SUPPORTEDor NOT SUPPORTED
