本文实例讲述了C#搜索TreeView子节点,保留父节点的方法。分享给大家供大家参考。具体如下：
C# 搜索TreeView子节点保留父节点：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 | private void selectNodeByName(string name){ //重新生生成树, InitTvCatalog(); //删除节点 selectNode(tvCatalog.Nodes, name);}private void selectNode(TreeNodeCollection nodes, string name){ bool del = true; for (int i = nodes.Count - 1; i >= 0; i--) { TreeNode node = nodes[i]; del = true; if (node.Nodes.Count != 0) { selectNode(node.Nodes, name); } if (node.Text.StartsWith(name, StringComparison.OrdinalIgnoreCase)) { del = false; } else { del = true; } if (del && node.Nodes.Count == 0) { node.Remove(); } } tvCatalog.ExpandAll();} |

希望本文所述对大家的C#程序设计有所帮助。
