c# - custom sorting in a bindinglist of keyvaluepairs -


i have bindinglist of keyvaluepair filled dynamicaly. 

  bindinglist<keyvaluepair<int, string>> homelist = new bindinglist<keyvaluepair<int, string>>();   foreach (listitem item in listbox2.items)     {      homelist.add(new keyvaluepair<int, string>(item.id, item.name));     }

the list has key(id) , value(text) shown

enter image description here

i want sort first 5 items asc , rest items asc.the sorting must value , not key. example: if have values : 4,5,8,7,6,10,9,3,2,1,22 sorting result must 4,5,6,7,8 ,1,2,3,9,10,22.any idea?

solved answer:

     public int compare(keyvaluepair<int,string> a, keyvaluepair<int,string> b)     {         return a.value.compareto(b.value);     }  list<keyvaluepair><int,>> playinglist = new list<keyvaluepair><int,>>();             (int = 0; < 5; ++)             {                 playinglist.add(homelist[i]);             }             playinglist.sort(compare);              list<keyvaluepair><int,>> benchlist = new list<keyvaluepair><int,>>();             (int = 5; < homelist.count(); i++)             {                 benchlist.add(homelist[i]);             }             benchlist.sort(compare);              //union 2 lists             var unionedlist = new list<keyvaluepair><int,>>();             unionedlist.addrange(playinglist.union(benchlist));              homelist.clear();             (int = 0; < unionedlist.count(); i++)             {                 homelist.insert(i, unionedlist[i]);             }             game.gethomelist = homelist;

the idea tony hopkinson said chop list two. sort them separately , join them togther.after clear bindlist , filled join list. sorting can applied in list<> , not bindlists<>.the answere in edited question
