dev的CheckedListBoxControl的使用

 chkcdess.DataSource = GlobalCache.Instace.AllCdes;//国家
            chkcdess.DisplayMember = "carea";
            chkcdess.ValueMember = "carea";

List<string> paras = model.cdess.Split(‘,‘).ToList();
            var data = chkcdess.DataSource as List<op_syscdes>;
            for (int i = 0; i < data.Count(); i++)
            {
                if (paras.Where(item => item.Trim() == data[i].carea).Count() > 0)
                {
                    chkcdess.SetItemChecked(i, true);
                }
            }

 List<string> cdes = new List<string>();
            foreach (op_syscdes item in chkcdess.CheckedItems)
            {

            }
            model.cdess = string.Join(",", cdes);
