TreeView的应用遍历节点问题

Question

现有如图所示的一个树,假如说目前已经获得到"海外图书"字符串,我如何遍历树节点才能得到它下面的子节点呢?("小说","读物"下面的曾子节点不取值)求大神赐教,在线等遍历treeview

Answer 1

public string GetCaseSuperiorList(string strAyMc)
        {
            TreeNode TargetTreeNote = null;
            Stack<TreeNode> TreeNoteStack = new Stack<TreeNode>();
            foreach (TreeNode tn in objTarget.Nodes)
            {
                TreeNoteStack.Push(tn);
            }
            while (TreeNoteStack.Count > 0)
            {
                TreeNode TempTreeNote = TreeNoteStack.Pop();
                if (TempTreeNote.Text == strAyMc)
                {
                    TargetTreeNote = TempTreeNote;
                    break;
                }
                else
                {
                    foreach (TreeNode tnChild in TempTreeNote.Nodes)
                    {
                        TreeNoteStack.Push(tnChild);
                    }
                }
            }
            List<TreeNode> lsResult = new List<TreeNode>();
            Stack<TreeNode> CaseSuperiorListStack = new Stack<TreeNode>();
            CaseSuperiorListStack.Push(TargetTreeNote);
            lsResult.Add(TargetTreeNote);
            while (CaseSuperiorListStack.Count > 0)
            {
                TreeNode TempTreeNote = CaseSuperiorListStack.Pop();
                foreach (TreeNode tnChild in TempTreeNote.Nodes)
                {
                    CaseSuperiorListStack.Push(tnChild);
                    lsResult.Add(tnChild);
                }
            }
            string strResult = string.Empty;
            foreach (TreeNode tnChild in lsResult)
            {
                strResult += "'" + tnChild.Text + "',";
            }
            return strResult.Substring(0, strResult.Length - 1);
        }这个方法是传进来节点名称,查找出下面所有节点的,我现在就是不想要曾子节点,只获取子节点

Answer 2

用我的代码找到你要的那个节点。然后它的Nodes属性就是你要的。

Answer 3

      TreeNode nodes = tvType.SelectedNode;         foreach (TreeNode tn in nodes)
                {
              //tn就是"海外图书"下面的子节点
                }
