前言

外观模式隐藏了子系统的复杂性，简化了客户端与子系统之间的交互。

代码

 public class Facade
 {
     private CommunicationModel communicationModel;
     private AcquisitionModel acquisitionModel;
     private ToolModel toolModel;

     public Facade()
     {
         communicationModel = new CommunicationModel();
         acquisitionModel = new AcquisitionModel();
         toolModel = new ToolModel();
     }

     public void Load()
     {
         communicationModel.Load();
         acquisitionModel.Load();
         toolModel.Load();
     }
 }

 // 通讯模块
 public class CommunicationModel
 {
     public void Load()
     {
         Console.WriteLine("Load communication model...");
     }
 }
 // 采集模块
 public class AcquisitionModel
 {
     public void Load()
     {
         Console.WriteLine("Load acquisition model...");
     }
 }

 //工具模块
 public class ToolModel
 {
     public void Load()
     {
         Console.WriteLine("Load tool model...");
     }
 }
 /*
  * 结构型模式：Structural Pattern
  * 外观模式：Facade Pattern
  */
 internal class Program
 {
     static void Main(string[] args)
     {
         Facade facade = new Facade();
         facade.Load();

         Console.ReadLine();
     }
 }
