怎样用递归遍历xml文件到TreeView

Answer 1

1.xml
----------------------------------------
<?xml version="1.0" encoding="utf-8"?>
<Test>
   <TestNode1>
       <ChildNode1/>
       <ChildNode2/>
       <ChildNode3/>
       <ChildNode4/>
   </TestNode1>
   <TestNode2>
       <ChildNode5/>
       <ChildNode6/>
   </TestNode2>
   <TestNode3>
       <ChildNode7/>
   </TestNode3>
</Test>XmlDocument xml = new XmlDocument();
xml.Load(@"C:\1.xml");
XmlNode root = xml.SelectSingleNode("Test");
TreeNode treeroot = new TreeNode(root.Name);
this.treeView1.Nodes.Add(treeroot);  //添加根节点
BindTreeView(root,treeroot);//---------------------------------------------------------private void BindTreeView(XmlNode node, TreeNode tn)
{
   foreach (XmlNode n in node.ChildNodes)
   {
     TreeNode childnode = new TreeNode(n.Name);
     tn.Nodes.Add(childnode);
     if (n.ChildNodes.Count > 0)
     {
       BindTreeView(n, childnode);
     }
   }
}

XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load("");
XmlNodeList xmlNodes = xmlDoc.DocumentElement.ChildNodes;
this.treeView1.BeginUpdate();
this.treeView1.Nodes.Clear();
XmlNode2TreeNode(xmlNodes, this.treeView1.Nodes);
this.treeView1.EndUpdate();        private void XmlNode2TreeNode(XmlNodeList xmlNode, TreeNodeCollection treeNode)
        {
            foreach (XmlNode var in xmlNode)
            {
                if (var.NodeType != XmlNodeType.Element)
                {
                    continue;
                }
                TreeNode newTreeNode = new TreeNode();
                newTreeNode.Text = var.Attributes["Title"].Value;
                if (var.HasChildNodes)
                {
                    if (var.ChildNodes[0].NodeType == XmlNodeType.CDATA)
                    {
                        newTreeNode.Tag = var.ChildNodes[0].Value;
                    }
                    XmlNode2TreeNode(var.ChildNodes, newTreeNode.Nodes);
                }
                treeNode.Add(newTreeNode);
            }
        }

你要编立什么样的XML啊
xml不一样，在遍历判断的就不一样啊！~~
