c# - 列表不会显示其内容

Question

我想制作一个显示当前开店的应用程序。每个商店都有一个名称，工作时间和类别。我做了一个包含每个商店及其属性的列表，但是当我使用foreach方法时，它不会显示其中的任何一个...您是否偶然知道问题出在哪里？或其他解决方法？

 class Shop
 {
    public string name;
    public DayOfWeek day{ get; set; }
    public TimeSpan start{ get; set; }
    public TimeSpan end{ get; set; }
    public string address{ get; set; }
    public string category{ get; set; }




    public Shop(string name, DayOfWeek day, TimeSpan start, TimeSpan end, string address, string category)
        {
        name = this.name;
        day = this.day;
        start = this.start;
        end = this.end;
        address = this.address;
        category = this.category;
        }
    }


    public openshops()
    {
        List<Shop> openShop = new List<Shop>();
        openShop.Add(new Shop("ill forno", DayOfWeek.Tuesday, new TimeSpan(18, 0, 0), new TimeSpan(00, 0, 0), "ermoupoli", "pizza"));
        openShop.Add(new Shop("Η ΣΥΡΑ", DayOfWeek.Sunday, new TimeSpan(12, 0, 0), new TimeSpan(00, 0, 0), "ermoupoli", "pizza"));
        openShop.Add(new Shop("ΠΙΤΑΚΙ", DayOfWeek.Tuesday, new TimeSpan(19, 30, 0), new TimeSpan(00, 30, 0), "ermoupoli", "souvlaki"));

        this.InitializeComponent();


        DayOfWeek today = DateTime.Today.DayOfWeek;
        TimeSpan now = DateTime.Now.TimeOfDay;
        if (today == DayOfWeek.Friday)
        {
            foreach (Shop shop in openShop)
            {
                if ((now > shop.start) && (now < shop.end))
                {
                    Button btn = new Button();
                    btn.Content = shop.name;
                    myStackPanel.Children.Add(btn);
                }

            }
        }
    }

除了确定如何设置属性外，开始时间和结束时间也有问题。

openShop.Add(new Shop("ill forno", DayOfWeek.Tuesday, new TimeSpan(18, 0, 0), new TimeSpan(00, 0, 0), "ermoupoli", "pizza"));
openShop.Add(new Shop("Η ΣΥΡΑ", DayOfWeek.Sunday, new TimeSpan(12, 0, 0), new TimeSpan(00, 0, 0), "ermoupoli", "pizza"));
openShop.Add(new Shop("ΠΙΤΑΚΙ", DayOfWeek.Tuesday, new TimeSpan(19, 30, 0), new TimeSpan(00, 30, 0), "ermoupoli", "souvlaki"));

这些 Shop对象的开始时间将大于结束时间，因此此 if语句

if ((now > shop.start) && (now < shop.end))

这些 Shop对象始终为false。我猜您实际上是想交换这些值。

openShop.Add(new Shop("ill forno", DayOfWeek.Tuesday, new TimeSpan(00, 0, 0), new TimeSpan(18, 0, 0), "ermoupoli", "pizza"));
openShop.Add(new Shop("Η ΣΥΡΑ", DayOfWeek.Sunday, new TimeSpan(00, 0, 0), new TimeSpan(12, 0, 0), "ermoupoli", "pizza"));
openShop.Add(new Shop("ΠΙΤΑΚΙ", DayOfWeek.Tuesday, new TimeSpan(00, 30, 0), new TimeSpan(19, 30, 0), "ermoupoli", "souvlaki"));
