怎么递归显示所有的注册表项到TreeView?　请高手帮改，先谢谢......
下面是代码：
private void 列出注册表所有的项()
{
RegistryKey rkey = Registry.CurrentUser.OpenSubKey("", true);
TreeNode aNode;
foreach (string s in rkey.GetSubKeyNames())
{
aNode = new TreeNode(s, 0, 0);
添加子节点(aNode, s);
treeView1.Nodes[0].Nodes.Add(aNode);
}
}
private void 添加子节点(TreeNode 父节点, string 条件)
{
RegistryKey rkey = Registry.CurrentUser.OpenSubKey(条件, true);
TreeNode aNode;
foreach (String s in rkey.GetSubKeyNames())
{
aNode = new TreeNode(s, 0, 0);
//添加子节点(aNode, s);
父节点.Nodes.Add(aNode);
}
}

[CODE]

private void button1_Click(object sender, System.EventArgs e)
{
TreeNode tn=new TreeNode("CurrentConfig");
treeView1.Nodes.Add(tn);
getAllkey(Registry.CurrentConfig,tn);

}

void getAllkey(RegistryKey key,TreeNode node)
{
foreach(string keystr in key.GetSubKeyNames())
{
TreeNode tn=new TreeNode(keystr);
node.Nodes.Add(tn);
RegistryKey tempkey=key.OpenSubKey(keystr);
getAllkey(tempkey,tn);

}
}

[/CODE]
