vb.net递归遍历操作TreeView控件树的实例代码

vb.net操作TreeView控件,生成树节点的实例代码,其中遍历采用递归方法。

-----------------------------------------------

Public Class Form2    Class nn        Public name As String        Public parent As String        Public snumber As String    End Class    Private Sub Form2_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load        Dim nd(10) As nn        Dim i As Integer        For i = 0 To 8            nd(i) = New nn        Next        nd(0).name = "root" : nd(0).parent = "0" : nd(0).snumber = "1"        nd(1).name = "aaa" : nd(1).parent = "1" : nd(1).snumber = "2"        nd(2).name = "bbb" : nd(2).parent = "1" : nd(2).snumber = "3"        nd(3).name = "ccc" : nd(3).parent = "2" : nd(3).snumber = "4"        nd(4).name = "ddd" : nd(4).parent = "3" : nd(4).snumber = "5"        nd(5).name = "eee" : nd(5).parent = "2" : nd(5).snumber = "6"        nd(6).name = "fff" : nd(6).parent = "2" : nd(6).snumber = "7"        nd(7).name = "ggg" : nd(7).parent = "5" : nd(7).snumber = "8"        Me.TreeView1.Nodes.Clear()               For i = 0 To 7            addto(nd(i), TreeView1.Nodes)        Next    End Sub    Public Sub addto(ByVal nd As nn, ByVal nodes As TreeNodeCollection)        Dim dd As TreeNode        Dim tmpd As TreeNode        If nd.parent = "0" Then            tmpd = nodes.Add(nd.name)            tmpd.ToolTipText = nd.snumber            Exit Sub        Else            For Each dd In nodes                If nd.parent = dd.ToolTipText Then                    tmpd = dd.Nodes.Add(nd.name)                    tmpd.ToolTipText = nd.snumber                    Exit Sub                End If                addto(nd, dd.Nodes)            Next        End If    End SubEnd Class
