Answer 1

最恨不懂装懂的人：

 foreach (TreeNode node in treeView1.Nodes) 
            { 
                if (node.Checked) 
                { 
                    MessageBox.Show(node.Text); 
                } 
            }

Answer 2

protected void TreeView1_SelectedNodeChanged(object sender, EventArgs e)
{
Response.Write(TreeView1.SelectedNode.Value);
}
protected void Button1_Click(object sender, EventArgs e)
{
if(TreeView1.SelectedNode!=null)
Response.Write("获取当前节点的value:" + TreeView1.SelectedNode.Value);
}
