html - Type or namespace not found -

-

hello doing assignment , program using visual studio 2012 lab getting error in behind code in .cs file error giving me line 20 , compilation error message says

the type or namespace name 'player' not found (are missing using directive or assembly reference?).

please me

line 18:     protected void addplayer(string name, int jersey, string team){ line 19:  line 20:         player player = new player(name, jersey); line 21:  line 22:         if ( string.equals(team, "team 1", stringcomparison.ordinalignorecase))

my whole code 

public partial class _default : system.web.ui.page {      protected void page_load(object sender, eventargs e)     {      }      protected void addplayer(string name, int jersey, string team){          player = new player(name, jersey);          if ( string.equals(team, "team 1", stringcomparison.ordinalignorecase))             listteam1.items.add(player.getname() + "-" + player.getjersey());         else if (string.equals(team, "team 2", stringcomparison.ordinalignorecase))             listteam2.items.add(player.getname() + "-" + player.getjersey());     }      protected int numplayers(string team)     {         if (string.equals(team, "team 1", stringcomparison.ordinalignorecase))             return listteam1.items.count;         else if (string.equals(team, "team 2", stringcomparison.ordinalignorecase))             return listteam2.items.count;         else             return 0;     }      protected void buttonleft_click(object sender, eventargs e)     {         string addeditem = listteam2.selecteditem.text;          listteam2.items.removeat(listteam2.selectedindex);         listteam1.items.add(addeditem);       }      protected void buttonright_click(object sender, eventargs e)     {         string addeditem = listteam1.selecteditem.text;          listteam1.items.removeat(listteam1.selectedindex);         listteam2.items.add(addeditem);      }      protected void buttonadd_click(object sender, eventargs e)     {         addplayer(tbname.text, int.parse(tbjersey.text), radioteam.selecteditem.text);          tbjersey.text = "";         tbname.text = "";     } }

when error, means says. doesn't know what player is, , therefore it's in namespace. need using directive imports namespace. if player in assembly, need add reference assembly.
