Interfaces

Home	»	C#	»	Interfaces

     In object-oriented paradigm, multiple inheritance are most challening to implement. Interfaces allow multiple inheritances in C#.
   An interface defines a contract. A class or struct that implements an interface must adhere to its contract. An interface may inherit from multiple base interfaces, and a class or struct may implement multiple interfaces.
   Interface can contain methods, properties, events, and indexer. The interface itself does not provide implements for the members that it defines. The interface merely specifies the members that must be supplied by classes or struct that implement the interface.

/* Interfaces - Multiple Inheritance */ using System; interface inter1; { void show(); } interface inter2; { void Display(); } class abc : inter1,inter2; { public void show() { Console.WriteLine("Show the Inter1 Method"); } public void Display() { Console.WriteLine("Display the Inter2 Method"); } } class abc1 { public static void Main() { abc obj = new abc(); obj.show(); obj.Display(); } }
