为什么我不能初始化我的Garage类？

Question

我有这个Car类，

public class Car 
{ 
    public string Name { get; set; } 
    public string Color { get; set; } 

    public Car(): this ("", "") { } 

    public Car(string name, string color) 
    { 
     this.Name = name; 
     this.Color = color; 
    } 
} 

另外我有一个包含Car个集合Garage类。

public class Garage 
    { 
     public List<Car> CarList { get; set; } 

     public Garage() { } 

     public Garage(int carCount) 
     { 
      this.CarList = new List<Car>(carCount); 
     } 

     public Garage(params Car[] cars) 
     { 
      this.CarList = new List<Car>(); 
      foreach (Car car in cars) 
       this.CarList.Add(car); 
     } 
    } 

我试图在Main()初始化Garage的实例，

Car car1 = new Car("BMW", "black"); 
Car car2 = new Car("Audi", "white"); 
Garage garage = new Garage(car1, car2); 

我得到一个错误，“一个字段初始不能引用非静态字段，方法或属性”。我做错了什么？ “

Answer 1

”实例字段不能用于初始化方法外的其他实例字段。“ 请检查此页ERROR page from MS。

所以要么使汽车物体静态为;

static Car car1 = new Car("BMW", "black"); 
    static Car car2 = new Car("Audi", "white"); 

    Garage garage = new Garage(car1, car2); 

或者 声明它

 Car car1 = new Car("BMW", "black"); 
    Car car2 = new Car("Audi", "white"); 
    Garage garagel; 

，然后任何其他方法

garage = new Garage(car1, car2);
