建造者模式是一种创建型设计模式，旨在让你能够创建复杂对象，而无需直接在应用程序中指定其具体类型。通过建造者模式，你可以将对象的构建过程和表示分离，从而使相同的构建过程可以创建不同表示形式的对象。这种模式通常包括以下几个关键组件：
-
产品（Product）：最终要创建的复杂对象。
-
抽象建造者（Builder）：声明了用于创建产品各个部件的方法接口。
-
具体建造者（Concrete Builder）：实现了抽象建造者接口，负责实际构建产品的各个部件。
-
指挥者（Director）：构建一个使用Builder接口的对象，负责按照一定顺序构建产品。
在使用建造者模式时，通常创建一个指挥者对象，然后将具体建造者对象传给指挥者，指挥者按照特定顺序调用建造者的方法来构建产品。这种模式的优势在于能够方便地构建复杂对象，同时将构建过程与表示分离，提高了灵活性和可维护性。

Builder
抽象建造者可以用接口和抽象类。
接口方式：
public interface IBuilder
{
/// <summary>
/// 手机
/// </summary>
IPhone Phone { get; set; }
/// <summary>
/// CPU
/// </summary>
void BuildCPU();
/// <summary>
/// 屏幕
/// </summary>
void BuildScreen();
/// <summary>
/// 内存
/// </summary>
void BuildMemory();
/// <summary>
/// 摄像头
/// </summary>
void BuildCamera();
/// <summary>
/// 电池
/// </summary>
void BuildBattery();
/// <summary>
/// 建构方法
/// </summary>
/// <returns></returns>
IPhone GetPhone();
}
抽象类方式：
public abstract class Builder
{
/// <summary>
/// 手机
/// </summary>
protected IPhone Phone { get; set; }
/// <summary>
/// CPU
/// </summary>
public abstract void BuildCPU();
/// <summary>
/// 屏幕
/// </summary>
public abstract void BuildScreen();
/// <summary>
/// 内存
/// </summary>
public abstract void BuildMemory();
/// <summary>
/// 摄像头
/// </summary>
public abstract void BuildCamera();
/// <summary>
/// 电池
/// </summary>
public abstract void BuildBattery();
/// <summary>
/// 建构方法
/// </summary>
/// <returns></returns>
public IPhone GetPhone()
{
return Phone;
}
}
Concrete Builder
建构苹果手机第一代
public class Iphone1Builder : IBuilder
{
/// <summary>
/// 苹果手机

public IPhone Phone { get; set; } = new ApplePhone();
public void BuildBattery()
{
Phone.Battery = "电池 内置1030毫安锂电池 ";
}
public void BuildCamera()
{

}
public void BuildCPU()
{

}
public void BuildMemory()
{

}
public void BuildScreen()
{
Phone.Screen = "屏幕 3.5英寸多点触控显示屏";
}
public IPhone GetPhone()
