Question

我有一类房子（这里没有显示频道枚举）

该类具有引用的对象和两个构造函数，然后在类中有一个名为“inventory”的List和两个或多个尝试访问列表的函数，我想要做的是使用相同的列表“班级房屋”内的所有独立功能但我得到一个'当前上下文中不存在'的错误，这让我觉得这是一个范围问题。但是所有的方法都在同一个“班级房屋”......它们的范围不同吗？

显然没有走正确的道路，我该如何看待这个？

class property
{
public string AddressNumber { get; set; }
        public string AddressStreet { get; set; }
        public double ListingPrice { get; set; }
        public double MonthlyRent { get; set; }
        public double Taxes { get; set; }
        public Channel Channel { get; set; }


        public property(string addnum, string addstreet, double lp, double mr, double taxes, Channel rorm)
        {
            AddressNumber = addnum;
            AddressStreet = addstreet;
            ListingPrice = lp;
            MonthlyRent = mr;
            Taxes = taxes;
            Channel = rorm;

        }
        public property()
        {
            AddressNumber = "4319";
            AddressStreet = "Forestview";
            ListingPrice = 600000;
            MonthlyRent = 0;
            Taxes = 2000;
            Channel = Channel.Rosa;

        }


      static  List<property> inventory = new List<property>
            {
                new property("19263","Collingham",24000,700,1744, Channel.Rosa),
                new property("16003","Collingham",24000,700,1672, Channel.Rosa),
                new property("13051","Bringard",24000,700,1305, Channel.Rosa),
                new property("10409","Bringard",24000,650,1591, Channel.Rosa),
                new property("10086","Marne",24000,650,1176, Channel.Rosa),
                new property("10042","Peerless",24000,650,1313, Channel.Rosa),
                new property("10736","Steel",30000,1000,1587, Channel.Mike),
                new property("2010","Glendale",30000,1000,1587, Channel.Mike),
                new property("2260","Blain",30000,1000,1587, Channel.Mike),
                new property("3000","Fullerton",30000,1000,1587, Channel.Mike),

            };

        property addtolist= new property("864", "Alter", 30000, 650, 1600, Channel.Rosa);
        inventory.Add(addtolist);


public static void userAddItem()
{
//I want to use the list here
}

public static void allItemsToFile()
{
//and here
}

} //end of house class bracket

您应该将您的类视为对象。所以你的家庭班可以只是一个定义房子的对象。

public class houses
{
    public string AddressNumber { get; set; }
    public string AddressStreet { get; set; }
    public double ListingPrice { get; set; }
    public double MonthlyRent { get; set; }
    public double Taxes { get; set; }
    public Channel Channel { get; set; }
}

现在，您想要列出属性。在你的主要课程中，你可以做这样的事情;

private List<houses> properties = new List<houses>();

houses house1 = new houses();

house1.AddressNumber = "19263";
house1.AddressStreet = "Collingham";
house1.ListingPrice = 24000.0;
hosue1.MonthlyRent = 700.0;
house1.Taxes = 1744.0;
house1.Channel = Channel.Rosa;

properties.Add(house1);

现在您有一个属性列表，您可以根据需要访问它们。

Foreach(houses h in properties)
{
    Console.WriteLine("{0},{1},{2},{3},{4},{5}", h.AddressNumber, h.AddressStreet, h.ListingPrice, h.MonthlyRent, h.Taxes, h.Channel.toString());
}

在许多函数中使用一个列表
