在C# 2005中怎样选中treeview中的一个节点.
在C#   2005中怎样选中treeview中的一个节点,
node.selected=true;
这个命令怎么不行了

------解决方案--------------------
public TreeNode FindTreeNode(String TreeNodeText, TreeNode Pnode )
{
foreach (TreeNode Cnode in Pnode.Nodes)
{
if (Cnode.Text == TreeNodeText)
{
return Cnode;
}

if (FindTreeNode(TreeNodeText, Cnode)==null)
{
return;
}
}
return null;
}
------解决方案--------------------
//--选择操作 最好是用checkbox直观..
//--treeview绑定例子
