主题：如何用目录树的节点形成组合框的列表值？

各位老师，想在目录树中用节点得到组合框的列表值，用了以下代码：

 

Dim tr1 As WinForm.TreeView = e.Form.Controls("TreeView1")
Dim cb As WinForm.ComboBox = e.Form.Controls("ComboBox1")
'选取节点进行排序
Dim nms As New List(of String)
For Each nd As WinForm.treenode In tr1.nodes
    nms.add(nd.name)
Next
nms.sort()
cb.ComboList = "nms"

 

但点击组合框时下面什么值都没有？请问是哪里不正确？

谢谢！

Dim tr1 As WinForm.TreeView = e.Form.Controls("TreeView1")
Dim cb As WinForm.ComboBox = e.Form.Controls("ComboBox1")
'选取节点进行排序
Dim nms As New List(of String)
For Each nd As WinForm.treenode In tr1.nodes
    nms.add(nd.name)
Next
nms.sort()
cb.ComboList = String.Join("|", nms.Toarray)

For Each nd As WinForm.treenode In tr1.nodes
  nms = nms  + "|" + nd.name
Next

谢谢！狐爸的那个是可以了，kylin老师的那个是遍历后那最后那一句cb.ComboList = ？要怎么写才可以呢？

Dim nms As String

Dim tr1 As WinForm.TreeView = e.Form.Controls("TreeView1")
Dim cb As WinForm.ComboBox = e.Form.Controls("ComboBox1")

For Each nd As WinForm.treenode In tr1.nodes
    nms = nms + "|" + nd.name
Next

cb.ComboList = nms
