-- 生成josn出现重复，怎么修正呢？
当前代码如下：
Dim cmd As New SQLCommand
cmd.C \'记得设置数据源名称
cmd.CommandText = "Se lect [_Identify],[_SortKey],卷宗名称,材料类别,材料名称,材料附件,材料guid From {View_juanzongcailiao} where 案件id=\'2b8ff1fa-2ed5-4cfd-ad3c-748616441a13\' "
Dim dt As DataTable = cmd.ExecuteReader
Dim drs As List(Of DataRow) = dt.Se lect("材料名称 is not null and 材料guid is not null", "_SortKey")
Output.Show(drs.Count)
Dim j As New JObject
Dim ja As New JArray
For Each dr As DataRow In drs
Dim jo As New JObject
jo("id") = dr("材料guid").ToString
jo("label") = dr("卷宗名称").ToString
\' jo("parentId") = "0"
\' jo("fujian") = dr("材料附件").ToString
\' jo("children") = GetNavigation1(dt, dr)
If Not ja.Contains(jo) Then
ja.Add(jo)
End If
Next
Output.Show(ja.ToString)
生成josn出现重复，怎么修正呢？ 想以材料guid为唯一值，一个值只出现一次！

-- 回复：（有点蓝）cmd.CommandText = "Select 卷宗名称...
如何实现根据label进行节点的调整，让label作为第一节点 然后以name作为第二节点呢？谢谢老师

For Each ss As String In dt.getvalues("卷宗名称")
生成第一节点
For Each ss2 As String In dt.getvalues("材料guid|材料名称","卷宗名称=\'" & ss & "\'")
生成第2节点
