vb.net从数据库读取信息填充treeview做成层次目录怎么做

给你一段我曾经写的代码,主要是生成TreeView的节点!有什么不懂的地方你就提!

Public Sub InitializeTreeView(ByVal strvXL As TreeView, ByVal vrsRecordTwo As DataSet)

Dim treBaseNodeOne As TreeNode

Dim treBaseNodeTwo As TreeNode

Dim strDWDM As String

m_rsRecordTwo = g_clsSybase.SelectSC_PD_SBCSB1()

'查找供电局信息

g_clsSybase.SelectRS_ZZJG_ZZJGDMB(m_rsRecordOne)

'添加根节点

Do While m_rsRecordOne.Read

strDWDM = m_rsRecordOne.GetString(0) '获取单位代码

treBaseNodeOne = New TreeNode

treBaseNodeOne.Text = m_rsRecordOne.GetString(1).Trim() '获取单位名称

treBaseNodeOne.Name = m_rsRecordOne.GetString(1)

treBaseNodeOne.Tag = ""

strvXL.Nodes.Add(treBaseNodeOne)

'添加树结构第二层

Dim drsTwo() As DataRow

drsTwo = m_rsRecordTwo.Tables(0).Select("SSDW='" strDWDM "' and SC__XLBM is null")

For Each dr As DataRow In drsTwo

treBaseNodeTwo = New TreeNode

treBaseNodeTwo.Text = dr.Item("XLMC").ToString.Trim

treBaseNodeTwo.Name = dr.Item("XLMC")

treBaseNodeTwo.Tag = dr.Item("XLBM")

treBaseNodeOne.Nodes.Add(treBaseNodeTwo)

Next

Loop

m_rsRecordOne.Close()

End Sub
