// Draw image to a Form.

public interface IDrawToForm

{

void Draw();

}

// Draw to buffer in memory.

public interface IDrawToMemory

{

void Draw();

}

// Render to the printer.

public interface IDrawToPrinter

{

void Draw();

}

Notice that each interface defines a method named Draw(). If you now wish to support each of

these interfaces on a single class type named Octagon, the compiler would allow the following defi-

nition:

class Octagon : IDrawToForm, IDrawToMemory, IDrawToPrinter

{

public void Draw()

{

// Shared drawing logic.

Console.WriteLine("Drawing the Octagon...");

}

}

Although the code compiles cleanly, you may agree we do have a possible problem. Simply put,

providing a single implementation of the Draw() method does not allow us to take unique courses of

action based on which interface is obtained from an Octagon object. For example, the following

code will invoke the same Draw() method, regardless of which interface we obtain:

static void Main(string[] args)

{

Console.WriteLine("***** Fun with Interface Name Clashes *****\n");
