The Program class creates an instance of the PrinterPortal class "injecting" the different implementations of the Bridge classes.
class Program
{
static void Main(string[] args)
{
PrinterPortal portal;
portal = new PrinterPortal(new PrinterBridge.InkJetPrinter()); Console.WriteLine(String.Format("{0}\n", portal.printOperation())); portal = null;
portal = new PrinterPortal(new PrinterBridge.LaserPrinter()); Console.WriteLine(String.Format("{0}\n", portal.printOperation())); portal = null;
portal = new PrinterPortal(new PrinterBridge.DotMatrixPrinter()); Console.WriteLine(String.Format("{0}\n", portal.printOperation())); portal = null;
Console.Read(); } }
portal = new PrinterPortal(new PrinterBridge.InkJetPrinter()); Console.WriteLine(String.Format("{0}\n", portal.printOperation())); portal = null;
portal = new PrinterPortal(new PrinterBridge.LaserPrinter()); Console.WriteLine(String.Format("{0}\n", portal.printOperation())); portal = null;
portal = new PrinterPortal(new PrinterBridge.DotMatrixPrinter()); Console.WriteLine(String.Format("{0}\n", portal.printOperation())); portal = null;
Console.Read(); } }
