DevExpress实现TreeList向上递归获取符合条件的父节点

/// <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 GetParentNode(this TreeListNode node, Predicate<TreeListNode> conditionHanlder){  TreeListNode _parentNode = node.ParentNode;//获取上一级父节点  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 = GetParentNode(_parentNode, conditionHanlder);  }  return _conditonNode;}

TreeListNode _node = e.Node;TreeListNode _condionParent = _node.GetParentNode(n => n.GetNodeType() == NodeType.Cab);//获取类型为CAB类型的父节点Trace.WriteLine(_condionParent.GetName());
