Syntax

• class DerivedClass : BaseClass
• class DerivedClass : BaseClass, IExampleInterface
• class DerivedClass : BaseClass, IExampleInterface, IAnotherInterface

Remarks

Classes can inherit directly from only one class, but (instead or at the same time) can implement one or more interfaces.

Structs can implement interfaces but cannot explicitly inherit from any type. They implicitly inherit from System.ValueType, which in turn inherits directly from System.Object.

Static classes cannot implement interfaces.
