动态从数据库中按遍历得方法填充到数得接点，如何将索引值付值给每个接点？？

TreeNode Folderitem=new TreeNode();
DDTreeView1.Nodes.Add(Folderitem);


下面给你个例子作为参考（读数据库）
//Folder（文件夹）和File(文件)
//T_Folder（文件夹表）T_File(文件表)

SqlConnection sqlCon =new SqlConnection("....");
SqlDataAdapter dataAdapter=new SqlDataAdapter("select FolderData_ID,Name from T_Folder",sqlCon);
DataSet dataSet=new DataSet();
sqlCon.Open();
dataAdapter.Fill(dataSet,"Folder");
sqlCon.Close();

foreach(DataRow Folderrow in dataSet.Tables["Folder"].Rows){
TreeNode Folderitem=new TreeNode();
SqlCommand filecmd=new SqlCommand("select FileData_ID,Name from T_File where Owner_ID="+Folderrow["FolderData_ID"].ToString(),sqlCon);
dataAdapter.SelectCommand=filecmd;
sqlCon.Open();

dataAdapter.Fill(dataSet,"File");
sqlCon.Close();
Folderitem.Text=Folderrow["Name"].ToString();
foreach(DataRow Filerow in dataSet.Tables["File"].Rows)
{
Fileitem=new TreeNode();

Fileitem.Text=Filerow["Name"].ToString();
Folderitem.Nodes.Add(Fileitem);
}
dataSet.Tables["File"].Clear();
DDTreeView1.Nodes.Add(Folderitem);
}
