c# - c#如何区分对象类型

Question

我正在创建一个显示 HomeTeam 的篮球 WPF 应用程序和一个 AwayTeam . 我创建了一个 Player对象并在主窗口中创建了 ObservableCollection主队(HomePlayersList)和客队(AwayPlayersList)的球员对象。我用过INotifyPropertyChanged播放器对象上的接口(interface)所以当IsInGame bool 为 true 玩家被添加到两个 ObservableCollection<Player> 之一取决于计数。 (如果列表一个 ObservableCollection<Player> HomeTeam 或 ObservableCollection<Player> AwayTeam 计数为 5，则其余的将添加到替换列表 ObservableCollection<Team> HomeSub 或 ObservableCollection<Team> AwaySub。)

但我试图区分球员是在主队还是客队，并且根据球员在哪个名单，球员将被添加到新的主队或客队名单中。

public static ObservableCollection<Player> HomePlayersList;
public static ObservableCollection<Player> AwayPlayersList;
public static ObservableCollection<Player> HomeTeam = new ObservableCollection<Player>();
public static ObservableCollection<Player> AwayTeam = new ObservableCollection<Player>();
public static ObservableCollection<Player> HomeSub = new ObservableCollection<Player>();
public static ObservableCollection<Player> AwaySub = new ObservableCollection<Player>();
public static int HomeSubCount = 7;

public class Player: INotifyPropertyChanged
{
    public static bool IsHome = true;
    private static int TotalSelected = 1;
    public string Id { get; set; }           //player ID
    public string FirstName { get; set; }    //player first name
    public string SecondName { get; set; }    //player second name
    public string KnownName { get; set; }     //player known name
    public string Position { get; set; }      //player position
    public string Number { get; set; }       //player number

    public bool isInGame;

    public bool IsInGame
    {
        get { return isInGame; }

        set
        {
            if (value != isInGame)
            {
                isInGame = value;

                if (isInGame)
                {
                    OnPropertyChanged("IsInGame", true);
                }
                else
                {
                    OnPropertyChanged("IsInGame", false);
                }
            }
        }
    }

    protected void OnPropertyChanged(PropertyChangedEventArgs e)
    {
        PropertyChangedEventHandler handler = PropertyChanged;
        if (handler != null)
            handler(this, e);
    }

    protected void OnPropertyChanged(string propertyName, bool state)
    {
        OnPropertyChanged(new PropertyChangedEventArgs(propertyName));

        if (state)
        {
            if (TotalSelected > 5 + MainWindow.HomeSubCount)
            {
                this.IsInGame = false;
                return;
            }

            if (MainWindow.HomeTeam.Count < 5)
                MainWindow.HomeTeam.Add(this);
            else
            {
                if (MainWindow.HomeSub.Count < MainWindow.HomeSubCount)
                {
                    MainWindow.HomeSub.Add(this);
                }
            }
            TotalSelected++;
        }
        else
        {

            if (SearchForMe(MainWindow.HomeTeam) != null)
            {
                MainWindow.HomeTeam.Remove(SearchForMe(MainWindow.HomeTeam));
                TotalSelected--;
                return;
            }

            if (SearchForMe(MainWindow.HomeSub) != null)
            {
                MainWindow.HomeSub.Remove(SearchForMe(MainWindow.HomeSub));
                TotalSelected--;
                return;
            }
        }
    }

    private Team SearchForMe(ObservableCollection<Team> OCT)
    {
        return OCT.Where(i => i.Number == this.Number).SingleOrDefault();
    }

    public event PropertyChangedEventHandler PropertyChanged;`enter code here`
}

在Player类中粘贴一个属性

ObservableCollection<Player> CurrnetIn { get; set; } 

并设置此属性，如果您将播放器添加到某个集合中。或者我误解了这个问题。
