我试图理解“类”的概念并编写一些简单的程序。但是我的函数 Check() 不正确。请跟我到右边..

namespace ConsoleApplication2
{
    public class Task
    {
        public string RusVer { get; set; } 
        public string Key { get; set; } 
        public string UserVer { get; set; }


        public void Check()
        {
            if (UserVer == Key)
                Console.WriteLine("Good");            
        }
    }

class Program
{
    static void Main(string[] args)
    {

        Task p1 = new Task();
        p1.RusVer = "??????, ???!";
        p1.Key = "Hello, World!";
        Console.WriteLine(p1.RusVer);
        Console.WriteLine("Translate it: ");
        p1.UserVer = Convert.ToString(Console.ReadLine());
        Console.WriteLine(p1.UserVer);

        Task.Check(); //errorCS0120

    }
}
}

我正在尝试使用EntityFramework添加一些实体.我需要和图像一样的模型 我创建了两个类:

public class PriceOfDish
{
    [Key]
    public virtual List<Dish> Dish_ID { get; set; }
    [Key]
    public DateTime DateTime { get; set; }

    public decimal Price { get; set; }
}
public class Dish
{
    [Key]
    public int Dish_ID { get; set; }
    public string DishName { get; set; }
    public string Description { get; set; }
    public virtual FoodCategory FoodCategory_ID { get; set; }
    public virtual Feature Feature_ID { get; set; }

    public virtual ICollection<OrderedDishes> Orders { get; set; …
