在VB.NET中将JSON字符串转换为数据集时面临的问题

Question

我正在尝试将一个API集成到我的项目中，该API返回JSON字符串。请检查以下示例JSON字符串。

{
    "records":{
        "Plan":[
            {
                "rs":{
                "**3 MONTHS**":"1611",
                "6 MONTHS":"2971",
                "1 YEAR":"5399"
                },
                "desc":"12 month SD pack + Rs 600 only",
                "plan_name":"Infinity",
                "last_update":"14-08-2018"
            },
            {
                "rs":{
                "1 MONTHS":"165",
                "3 MONTHS":"499",
                "6 MONTHS":"994",
                "1 YEAR":"1819"
                },
                "desc":"11M +1M Free",
                "plan_name":"South My Plan 99",
                "last_update":"14-08-2018"
            },
            {
                "rs":{
                "1 MONTHS":"219",
                "3 MONTHS":"656",
                "6 MONTHS":"1313",
                "1 YEAR":"2408"
                },
                "desc":"11M + 1M Free",
                "plan_name":"Freedom Entertainment",
                "last_update":"01-01-1970"
            }
        ]
    },
    "status":1
}

现在，我正在尝试使用以下方法在数据集中转换上述字符串。

    Public Function GetJsonArrayToDataSet(ByVal sJsonData As String) As DataSet
    Dim dSetJson As New DataSet
    Dim xDoc As New XmlDocument
    Dim sJsonXML As String = String.Empty
    Try
        sJsonData = Replace(sJsonData, "'", "")
        sJsonData = "{""rootNode"": " & sJsonData & " }"
        xDoc = JsonConvert.DeserializeXmlNode(sJsonData, "rootNode")
        If xDoc IsNot Nothing Then
            sJsonXML = xDoc.OuterXml
            dSetJson.ReadXml(New StringReader(sJsonXML))

            Return dSetJson
        Else
            Return Nothing
        End If
    Catch ex As Exception
        Return Nothing
    End Try
End Function

在这里出现如下错误

The ' ' character, hexadecimal value 0x20, cannot be included in a name.***

因为空格在关键部分中。我还尝试手动从键中删除空间，然后再次检查，但出现如下错误：

Name cannot begin with the '3' character, hexadecimal value 0x33. Line 1, position 41.

请告诉我上述问题的解决方法。
