Implementing an Interface Visual C Sharp 2010

To implement an interface, you declare a class or structure that inherits from the interface and that implements all the methods specified by the interface . For example, suppose you are defining the Mammal hierarchy but you need to specify that land-bound mammals provide a method named NumberOfLegs that returns as an int the number of legs that a mammal has . (Sea-bound mammals do not implement this interface .) You could define the ILandBound interface that contains this method as follows:


interface ILandBound 
{ 
    int NumberOfLegs(); 
}

You could then implement this interface in the Horse class . You inherit from the interface and provide an implementation of every method defined by the interface .

 
class Horse : ILandBound 
{ 
    ... 
    public int NumberOfLegs()  
    { 
        return 4; 
    } 
}
