建造者模式-C#改良实现

区分网上已有的一般建造者模式实现，个人觉得实现太单一了，自己google查了一些好的实现，挑了其中比较适合的，做个笔记。

    # region 标准Builder模式实现

    // 产品

    class Television

    {

        public string Code { get; set; }

        public string DisplayTechnology { get; set; }

        public string HDFormat { get; set; }

        public string ScreenType { get; set; }

        public string Size { get; set; }

        public string Feature { get; set; }

    }

    // 抽象Builer

    abstract class TelevisionBuilder{

        protected Television television;

        public abstract void SetCode();//ProductCode

        public abstract void SetDisplayTechnology(); //LCD, LED, OLED, Plasma, CRT

        public abstract void SetHDFormat(); // Full HD, HD Ready, Ultra HD, None

        public abstract void SetScreenType(); //Curved, Flat, Standard

        public abstract void SetSize(); // 22, 32, 40, 42, 54

        public abstract void SetFeature(); //3D, Smart, Standard , HDMI Ports, USB Ports, Built in WIFI, Ethernet, Remote

        //获取产品

        public Television Television { get => television; }

    }

    // 具体Builder（具体实现1）

    class FullHD40TVBuilder : TelevisionBuilder

    {

        public FullHD40TVBuilder() => television = new Television();

        public override void SetCode() => television.Code = "FullHD40TV";

        public override void SetDisplayTechnology() => television.DisplayTechnology = "LCD";

        public override void SetHDFormat() => television.HDFormat = "FullHD";

        public override void SetScreenType() => television.ScreenType = "Flat";

        public override void SetSize() => television.Size = "40";

        public override void SetFeature() => television.Feature = "1 HDMI Ports, 1 USB Ports, Remote";

    }

    // 具体Builder（具体实现2）

    class SMARTLED54TVBuilder : TelevisionBuilder

    {

        public SMARTLED54TVBuilder() => television = new Television();

        public override void SetCode() => television.Code = "SMARTLED54TV";

        public override void SetDisplayTechnology() => television.DisplayTechnology = "LED";

        public override void SetHDFormat() => television.HDFormat = "FullHD";

        public override void SetScreenType() => television.ScreenType = "Flat";

        public override void SetSize() => television.Size = "54";

        public override void SetFeature() => television.Feature = "2 HDMI Ports, 2 USB Ports, Built in WIFI, Ethernet, Remote";

    }

    // 环境角色（解耦作用）

    class TelevisionContext {

        public void Construction(TelevisionBuilder builder)

        {

            builder.SetCode();

            builder.SetDisplayTechnology();

            builder.SetFeature();

            builder.SetHDFormat();

            builder.SetScreenType();

            builder.SetSize();

        }

    }

    #endregion

    // 在客户端调用：

    var builder1 = new SMARTLED54TVBuilder();

    var builder2 = new FullHD40TVBuilder();

    var ctx = new TelevisionContext();

    ctx.Construction(builder1);

    ctx.Construction(builder2);

    var product1 = builder1.Television;

    var product2 = builder2.Television;

    Console.WriteLine($"产品1生产完成，详细：{JsonConvert.SerializeObject(product1)}");

    Console.WriteLine($"产品2生产完成，详细：{JsonConvert.SerializeObject(product2)}");

相比较来讲，这个实现更细致，而且充分利用了C#的基本语法，并没有额外在创建一个函数返回产品，相对更简洁更"高大上"，哈哈....
