1.  上端来指定系列，尺寸，饼皮和酱料

 

 static void Main(string[] args)
        {
            try
            { 
               {
                     Console.WriteLine("************************************************************");
                    TipcalPizzaBridge pizza = new TipcalPizzaBridge()
                    {
                        size = new SizeSmall(),
                        sause = new KoreanSauce(),
                        bake = new BakeThick()
                    };
                     pizza.MakePizza();               
               }
               {
                    Console.WriteLine("************************************************************");
                    KingPizzaBridge pizza = new KingPizzaBridge()
                    {
                       size = new SizeBig(),
                       sause = new ItalianSauce(),
                       bake = new BakeManual()
                    };
                    pizza.MakePizza();
                }
               {
                    Console.WriteLine("************************************************************");
                    EconomicPizzaBridge pizza = new EconomicPizzaBridge()
                    {
                        size = new SizeBig(),
                        sause = new BBQSauce(),
                        bake = new BakeThin()
                    };
                    pizza.MakePizza();
                }
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }
            Console.ReadKey();
        }
    }

 

 

 

2. 在系列中定义桥接，类的组合

 

namespace BridgePattern.Pizza
{
    class TipcalPizzaBridge:IPizza 
    {
        public ISize size { get; set; }
        public ISauce sause { get; set; }
        public IBake bake { get; set; }

        public void MakePizza()
        {
            Console.WriteLine("Customer need a TipcalPizza");
            size.PizzaSize();
            sause.Sauce();
            bake.Bake();
        }
    }
}
