| Term
| Interface
|
| Definition
| Reference type containing only abstract members—delegates, events, indexers, public methods, properties. The interface contains only member declarations. A class implementing an interface must provide the implementation of the interface members. An interface cannot contain constants, constructors, data fields, destructors, or static members. Interface member declarations are implicitly public. Classes or structs may inherit any number of interfaces.
A C# interface is declared with the interface keyword.
