Convert XML to JSON and then deserialize to object

Question

I'm developing an ASP.NET MVC application with .Net Framework 4.7 and JSON.NET 10.0.2.

I want to load a xml document, convert it to JSON and then deserialize to object. I want to do this because I want to use JSON files and also XML files.

This is the class I want to create with the file:

public class ProductionOrderFile
{
    public string ProductionOrderName { get; set; }
    public string ProductCode { get; set; }
    public List<Batch> Batches { get; set; }
    public List<AggregationLevelConfiguration> Levels { get; set; }
    public List<VariableData> VariableData { get; set; }
}

This is the class that deserialize to the object:

private ProductionOrderFile ParseProductionOrderFile(Stream inputStream)
{
    var serializer = new JsonSerializer();
    XmlDocument doc = new XmlDocument();
    doc.Load(inputStream);

    string jsonText = JsonConvert.SerializeXmlNode(doc);

    return JsonConvert.DeserializeObject<ProductionOrderFile>(jsonText);
}

This is the XML document:

<ProductionOrderFile>
    <ProductionOrderName>"ProOrd_Xml_001"</ProductionOrderName>
    <ProductCode>Pro_EU_001</ProductCode>
    <Batches>
        <Name>Lote_Xml_01</Name>
    </Batches>
    <Levels>
        <Id>1</Id>
        <Name>Nivel_1</Name>
        <PkgRatio>120</PkgRatio>
    </Levels>
    <Levels>
        <Id>2</Id>
        <Name>Nivel_2</Name>
        <PkgRatio>1</PkgRatio>
    </Levels>
    <VariableData>
        <VariableDataId>01</VariableDataId>
        <LevelId>1</LevelId>
        <Value>Pro_EU_001</Value>
    </VariableData>
    <VariableData>
        <VariableDataId>20</VariableDataId>
        <LevelId>1</LevelId>
        <Value>Lote_Xml_01</Value>
    </VariableData>
    <VariableData>
        <VariableDataId>11</VariableDataId>
        <LevelId>1</LevelId>
        <Value>170101</Value>
    </VariableData>
    <VariableData>
        <VariableDataId>17</VariableDataId>
        <LevelId>1</LevelId>
        <Value>210101</Value>
    </VariableData>
    <VariableData>
        <VariableDataId>21</VariableDataId>
        <LevelId>1</LevelId>
        <Value>####################</Value>
    </VariableData>
</ProductionOrderFile>

And this is the jsonText var content:

{
    "ProductionOrderFile": {
        "ProductionOrderName": "\"ProOrd_Xml_001\"",
        "ProductCode": "Pro_EU_001",
        "Batches": {
            "Name": "Lote_Xml_01"
        },
        "Levels": [{
            "Id": "1",
            "Name": "Nivel_1",
            "PkgRatio": "120"
        }, {
            "Id": "2",
            "Name": "Nivel_2",
            "PkgRatio": "1"
        }],
        "VariableData": [{
            "VariableDataId": "01",
            "LevelId": "1",
            "Value": "Pro_EU_001"
        }, {
            "VariableDataId": "20",
            "LevelId": "1",
            "Value": "Lote_Xml_01"
        }, {
            "VariableDataId": "11",
            "LevelId": "1",
            "Value": "170101"
        }, {
            "VariableDataId": "17",
            "LevelId": "1",
            "Value": "210101"
        }, {
            "VariableDataId": "21",
            "LevelId": "1",
            "Value": "####################"
        }]
    }
}

But this return JsonConvert.DeserializeObject<ProductionOrderFile>(jsonText); returns an instance of ProductionOrderFile with all of its properties null.

Maybe the problem is that the XML document doesn't have the right format.

Has the XML document the right format? What am I doing wrong?
