关键代码:
/// <summary> /// 向上递归,获取符合条件的父节点 /// </summary> /// <param name="node">需要向上递归的节点</param> /// <param name="conditionHanlder">判断条件【委托】</param> /// <returns>符合条件的节点【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))//判断上一级父节点是否符合要求 { _conditonNode = _parentNode; } if (_conditonNode == null)//若没有找到符合要求的节点,递归继续 _conditonNode = GetSelfParentNode(_parentNode, conditionHanlder); } return _conditonNode; }
代码使用:
TreeListNode _node = e.Node;
TreeListNode _condionParent = _node.GetSelfParentNode(n => n.GetNodeType() == NodeType.Cab);//获取类型为CAB类型的父节点
Trace.WriteLine(_condionParent.GetName());
