        private void FindNode(TreeNode pnode, string content)
        {
            TreeNodeCollection nodes = pnode==null?treeView1.Nodes:pnode.Nodes;
            foreach (TreeNode node in nodes)
            {
                if (node.Text == content)
                {
                    treeView1.SelectedNode = node;
                    return;
                }
                else
                {
                    FindNode(node, content);
                }
            }
        }

使用
FindNode(null, "宣北县")

你试试，我没测试

遍历treeview中的节点，相等的就选中。
