wpf - How distinguish between objects type c# -

i creating basketball wpf app displays hometeam , awayteam. have created player object , in main window have created observablecollection of player objects both home (homeplayerslist) , away teams (awayplayerslist). have used inotifypropertychanged interface on player object when isingame bool true player gets added 1 of 2 observablecollection<player> depending on count. (if list 1 observablecollection<player> hometeam or observablecollection<player> awayteam count 5, rest gets added substitution list observablecollection<team> homesub or observablecollection<team> awaysub.)

but trying distinguish whether player in home or away team, , depending on list player in, player added new list of home or away.

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     {         { 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` } 

paste in player class property

observablecollection<player> currnetin { get; set; }  

and set property, if add player in collection. or have misunderstood question.
