小编str*_*rax的帖子

我使用的是Windows 7,Visual Studio 2013,C#和.NET 4.5.

我的问题是以下行的输出:

 Console.WriteLine("Car`s value: {0:C} ", myNewCar.determineMarketValue());

myNewCar.determineMarketValue() 返回一个double.

我该如何解决这个问题？

我的输出是这样的:

using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

{
    class Program
    {

        static void Main(string[] args)
        {
            Car myNewCar = new Car();
            myNewCar.Make = "Oldsmobile";
            myNewCar.Model = "Cutlas Supreme";
            myNewCar.Year = 1986;
            myNewCar.Color = "Silver";

            Console.OutputEncoding = System.Text.Encoding.Unicode; 

                Console.WriteLine("{0} - {1} - {2}",
                myNewCar.Make,
                myNewCar.Model,
                myNewCar.Color);


            Console.WriteLine("Car`s value: {0:C} ", myNewCar.determineMarketValue());

            Console.ReadLine();
        }

    }

    class Car
