vb.net datatable序列化为json

我有这种表：

我需要获得这个JSON(当然命令可以是任何,结构/树是最重要的)：

数据表可以更改,因此序列化应该是动态的.我正在使用vb.net并使用此代码：

Public Function GetJson() As String
        Dim dt As New System.Data.DataTable
        dt = CreateDataTable() 'here I retrive data from oracle DB
        Dim serializer As New System.Web.Script.Serialization.JavaScriptSerializer()
        Dim packet As New List(Of Dictionary(Of String,Object))()
        Dim row As Dictionary(Of String,Object) = nothing
        For Each dr As DaTarow In dt.Rows
            row = New Dictionary(Of String,Object)()
            For Each dc As DataColumn In dt.Columns
                row.Add(dc.ColumnName.Trim(),dr(dc))
            Next
            packet.Add(row)
        Next
        Return serializer.Serialize(packet)
    End Function

但是这段代码给我带来了不好的json：[{“NAME”：“city”,“PARENT”：“address”,“VALUE”：“have child”},{“NAME”：“coordinates”,“PARENT”：“地址“,”VALUE“：”有孩子“},{”NAME“：”街道“,”父母“：”地址“,”VALUE“：”有孩子“} …….

有人可以帮助我吗？

‘哦 – 不,你没有’版本：

Public Function GetJson(ByVal dt As DataTable) As String
    Return New JavaScriptSerializer().Serialize(From dr As DaTarow In dt.Rows Select dt.Columns.Cast(Of DataColumn)().ToDictionary(Function(col) col.ColumnName,Function(col) dr(col)))
End Function
