An urgent question about the checkbox in treeview in asp.net ~~

q197688

I added the showcheckbox attribute when I was doing treeview, but because I did n’t know how to add the id of the selected node to the database for the first time, my treeview is database-bound. Please help me, it is better to have detailed code, thank you ~~

foreach (TreeNode node in tnBaseNode.Nodes)
{
  if (node.Checked == true)
  {
     // Insert data
  }
}

        {
            ArrayList arr = new ArrayList();
            foreach (TreeNode node in TreeView1.Nodes)
            {
                if (node.Checked == true)
                {
                    arr.Add(node.Value);//node.Value is the bound ID
                }
            }
            . . . . . //Add code to the database
        }
