10. Explicit interface implementation

IntermediateMediumLesson 10 of 15

Used when two interfaces have the same member, or to hide a member from the class's public API.

csharp

public interface IPrinter { void Print(); }
public interface IScanner { void Print(); }   // same name

public class Mfp : IPrinter, IScanner
{
    void IPrinter.Print() => Console.WriteLine("printing");
    void IScanner.Print() => Console.WriteLine("printing scan log");
}

var m = new Mfp();
((IPrinter)m).Print();   // only callable through the interface
