当一个类有两个维度的变化时，我们就可以用组合替代继承，那么就可以避免继承带来的重复代码书写。
using System;
using System.Collections;
using System.Collections.Generic;
using System.Linq;
namespace ConsoleApplication1
{
class Program
{
public abstract class Color
{
public string col;
}
public class RedColor : Color
{
public RedColor()
{
col = "red";
}
}
public class BlueColor : Color
{
public BlueColor()
{
col = "blue";
}
}
public abstract class Car
{
private Color color;
public Color Color
{
get { return color; }
set { color = value; }
}
public abstract void Show();
}
public class BigCar : Car
{
public override void Show()
{
Console.WriteLine("big car " + Color.col);
}
}
public class SmallCar : Car
{
public override void Show()
{
Console.WriteLine("small car " + Color.col);
}
}
static void Main(string[] args)
{
