各位新年好,有个问题，关于XML的，帮我看下，谢了，具体看内宾

[ylm7979]

内宾如下：
<?xml version="1.0" encoding="utf-8" ?>
<NotePapers >
<Folder FolderID="1" FolderName="未存档的">
<NotePaper NoteID="1" Title="今日便签1">
</NotePaper>
<NotePaper NoteID="2"Title="今日便签1">
</NotePaper>
</Folder>
<Folder FolderID="2" FolderName="自定义">
<NotePaper NoteID="3" Title="今日便签2">
</NotePaper>
<NotePaper NoteID="4" Title="今日便签2">
</NotePaper>
</Folder>
</NotePapers>
问用DataSet 怎么样建树，要显示的数据（字段）（FolderName 下面有Title）
也就是"未存档的"的下一层是"今日便签1"和"今日便签1"
"自定义"的下一层是"今日便签2"和"今日便签2"

"未存档的"和"自定义"是同一级的，谢了

TreeNode tParent=new TreeNode();
tParent.Text="文件";

DataView dv = new DataView();
dv = ds.Tables["Folder"].DefaultView;
TreeNode node;
for(int i=0;i<dv.Count;i++)
{
node = new TreeNode();
node.ID =dv[i]["FolderID"].ToString();
node.Text =dv[i]["FolderName"].ToString();
tParent.Nodes.Add(node);
// DataView dvHasChildNodes = new DataView();
// dvHasChildNodes = ds.Tables["NotePaper"].DefaultView;
// TreeNode nodechild;
// for( int k=0;k<dvHasChildNodes.Count;k++)
// {
// nodechild = new TreeNode();
// // nodechild.ID =dv[k]["NoteID"].ToString();
// nodechild.Text =dv[k]["Title"].ToString();
// node.Nodes.Add(nodechild);
// }
}
nodes.Add(tParent);
这样怎么不行
