Explicit Interface Implementation

When a concrete type implements an interface implicitly, the interface methods also become part of the public contract of the concrete type itself. However, you might not always want the interface method implementations to become part of the public interface of the class that implements the interface. In this way I cannot access members through a class instance. When you need this behaviour in your own types, you can use the explicit interface implementation syntax.

You have design three custom interfaces

Now you can look the explicit interface implementation:

To access the required functionality, you make use of explicit casting:

Explicit interface implementation also allows the programmer to inherit two interfaces that share the same member names, as the example above.
