場景

使用不同策略封裝命令

實現代碼

命令封裝接口

namespace DesignPatterns.Strategy {/// <summary>/// 命令封裝接口/// </summary>public interface IPacket{/// <summary>/// 分裝數據/// </summary>/// <returns>數據對象</returns>void Packet();} }

抽象命令封裝類

namespace DesignPatterns.Strategy {/// <summary>/// 命名打包抽象類/// </summary>public abstract class AbstractPacket{/// <summary>/// 命令長度/// </summary>protected int Len;/// <summary>/// 命令數組/// </summary>protected byte[] Datas = new byte[256];/// <summary>/// 獲取命令長度/// </summary>/// <returns></returns>public int GetLen(){return this.Len;}/// <summary>/// 獲取命令/// </summary>/// <returns></returns>public byte[] GetDatas(){return this.Datas;}} }

命令A封裝實現

namespace DesignPatterns.Strategy {/// <summary>/// A命令打包類/// </summary>public class PacketA : AbstractPacket, IPacket{/// <summary>/// 打包命令/// </summary>public void Packet(){this.Len = 20;for (int i = 0; i < this.Len; i++){this.Datas[i] = 0x00;}}} }

命令B封裝實現

namespace DesignPatterns.Strategy {/// <summary>/// B命令打包類/// </summary>public class PacketB : AbstractPacket, IPacket{/// <summary>/// 打包命令/// </summary>public void Packet(){this.Len = 50;for (int i = 0; i < this.Len; i++){this.Datas[i] = 0x10;}}} }

相關調用

IPacket packetA = new PacketA(); IPacket packetB = new PacketB(); packetA.Packet(); packetB.Packet(); Console.WriteLine(((AbstractPacket)packetA).GetLen()); Console.WriteLine(((AbstractPacket)packetB).GetLen());

Out:

20 50
