[WinForm][DevExpress][TreeList]向上遞迴，擷取合格父節點

標籤：winform   style   class   code   ext   color   

關鍵代碼：

       /// <summary>        /// 向上遞迴，擷取合格父節點        /// </summary>        /// <param name="node">需要向上遞迴的節點</param>        /// <param name="conditionHanlder">判斷條件【委託】</param>        /// <returns>合格節點【TreeListNode】</returns>        public static TreeListNode GetSelfParentNode(this TreeListNode node, Predicate<TreeListNode> conditionHanlder)        {            TreeListNode _parentNode = node.ParentNode;            TreeListNode _conditonNode = null;            if (_parentNode != null)            {                if (conditionHanlder(_parentNode))//判斷上一級父節點是否符合要求                {                    _conditonNode = _parentNode;                }                if (_conditonNode == null)//若沒有找到符合要求的節點，遞迴繼續                    _conditonNode = GetSelfParentNode(_parentNode, conditionHanlder);            }            return _conditonNode;        }

代碼使用：

            TreeListNode _node = e.Node;            TreeListNode _condionParent = _node.GetSelfParentNode(n => n.GetNodeType() == NodeType.Cab);//擷取類型為CAB類型的父節點            Trace.WriteLine(_condionParent.GetName());
