i need remove till specific item, for example till [1]. that means in my list are just 2 items [0] and [1]. how do that with c#?

You can use the List.RemoveWhere(Predicate).. Alternatively, you can do a for loop - looping backwards, removing items till the item you're after ie

for(var i = List.Count()-1; i>=0; i--) {
   var item = List[i];
   if (item != "itemThatYourLookingFor") {
      List.Remove(item);
      continue;
   }
   break;
}
