怪了，非常简单的树形结构循环加载问题

[liang4571231]

共有三级：

TreeNode tnCC1 = new TreeNode("以前", "01");
TreeNode tnCC2 = new TreeNode("上周", "02");
TreeNode tnCC3 = new TreeNode("本周", "03");
TreeNode tnCC4 = new TreeNode("今天", "04");

TreeNode tnC1 = new TreeNode("满意度分析", "01");
TreeNode tnC2 = new TreeNode("回访满意度分析", "02");
TreeNode tnC3 = new TreeNode("业务分类分析", "03");

TreeNode tnP1 = new TreeNode("投诉", "TS");
TreeNode tnP2 = new TreeNode("特服", "TF");
TreeNode tnP3 = new TreeNode("报修", "BX");
TreeNode tnP4 = new TreeNode("报案", "BA");
TreeNode tnP5 = new TreeNode("问询", "WX");
TreeNode tnP6 = new TreeNode("建议", "JY");

List<TreeNode> tnCCList = new List<TreeNode>();
tnCCList.Add(tnCC1);
tnCCList.Add(tnCC2);
tnCCList.Add(tnCC3);
tnCCList.Add(tnCC4);

List<TreeNode> tnCList = new List<TreeNode>();
tnCList.Add(tnC1);
tnCList.Add(tnC2);
tnCList.Add(tnC3);

List<TreeNode> tnPList = new List<TreeNode>();
tnPList.Add(tnP1);
tnPList.Add(tnP2);
tnPList.Add(tnP3);
tnPList.Add(tnP4);
tnPList.Add(tnP5);
tnPList.Add(tnP6);

foreach (TreeNode tnP in tnPList)
{
foreach (TreeNode tnC in tnCList)
{
foreach (TreeNode tnCC in tnCCList)
{
tnC.ChildNodes.Add(tnCC);
}
tnP.ChildNodes.Add(tnC);
}
tvwAnalyse.Nodes.Add(tnP);
}

//foreach (TreeNode tnP in tnPList)
//{
// tvwAnalyse.Nodes.Add(tnP);
// foreach (TreeNode tnC in tnCList)
// {
// tvwAnalyse.Nodes[tvwAnalyse.Nodes.Count - 1].ChildNodes.Add(tnC);
// foreach (TreeNode tnCC in tnCCList)
// {
// tvwAnalyse.Nodes[tvwAnalyse.Nodes.Count - 1].ChildNodes[tvwAnalyse.Nodes[tvwAnalyse.Nodes.Count - 1].ChildNodes.Count - 1].ChildNodes.Add(tnCC);
// }

// }

//}


第一级节点能全部显示，第二级节点只能显示第一级最后节点的子节点，第三级节点只能显示第一级最后节点的第二级最后节点的子节点，为什么？
描述的不知大家听明白没，贴个图吧，不知道能不能贴图

图片，不知能显示不能

我再贴图片：

一个节点实例只能为另外一个节点的子节点..


foreach (TreeNode tnP in tnPList)
{
TreeNode _tnp = new TreeNode(tnP.Text, tnP.Value);
foreach (TreeNode tnC in tnCList)
{
TreeNode _tnC = new TreeNode(tnC.Text, tnC.Value);
foreach (TreeNode tnCC in tnCCList)
{
_tnC.ChildNodes.Add(new TreeNode(tnCC.Text, tnCC.Value));
}
_tnp.ChildNodes.Add(_tnC);
}
TreeView1.Nodes.Add(_tnp);
}
