我如何能从list<string>中，优先取出“I3004001”？

public M_ItemInfo GetCangBao()
{
M_ItemInfo fItem = null;
List lings = new List(new string[] { "I3004001", "I3002001", "I3001001", "I3000001" });

        foreach (var item in lings)
        {
            fItem = GameData.packCenter.GetItemInfo(item);
            if (fItem != null)
            {
                break;
            }
        }
        return fItem;
    }

foreach (var item in lings.OrderBy(x => x == "I3004001" ? 0 : 1))
