How to convert JSON to XML in C#

I have objects such as :

public class MyObject
{
    public string OrderId { get; set; }
    public string Installment { get; set; }
    public string Amount { get; set; }
    public List<Product> Products { get; set; }
}
public class Product
{
    public string ProductCode { get; set; }
    public string ProductName { get; set; }
    public string Quantity { get; set; }
    public string Price { get; set; }
}

I am trying to convert MyObject to XML with NewtonSoft.

I did not found directly convert an object to XML doc in NewtonSoft docs (NwetonSOftDocs)

So I thought, I can first convert MyObject to JSON then I can convert to XML but it did not work.

Helper Class:

    public static XNode XmlSerialize<T>(T ToXml, string root, JsonSerializerSettings settings)
    {
        var ToJson = JsonConvert.SerializeObject(ToXml, Newtonsoft.Json.Formatting.Indented, settings);
        return JsonConvert.DeserializeXNode(ToJson, root);
    }

public static JsonSerializerSettings DefaultJsonSerializerSettings()
{
    return new JsonSerializerSettings { ContractResolver = new CamelCasePropertyNamesContractResolver(),
        DefaultValueHandling = DefaultValueHandling.Ignore,
        NullValueHandling = NullValueHandling.Ignore,
        
    };
}

I tested in Console:

static void Main(string[] args)
        {
            XNode xml = Helper.XmlSerialize<MyObject>(new MyObject{ Amount = "100", OrderId = "123123123", Installment="1", Products = new List<Product> { new Product { ProductName = "Test", Price = "100" }, new Product { ProductName = "Test2", Price = "200" } } }, "auth", Helper.DefaultJsonSerializerSettings());

            Console.WriteLine(xml.ToString());


            Console.ReadKey();
        }

Output:

<auth>
  <orderId>123123123</orderId>
  <installment>1</installment>
  <amount>100</amount>
  <products>
    <productName>Test</productName>
    <price>100</price>
  </products>
  <products>
    <productName>Test2</productName>
    <price>200</price>
  </products>
</auth>

What i want :

<auth>
  <orderId>123123123</orderId>
  <installment>1</installment>
  <amount>100</amount>
  <products>
   <product>
    <productName>Test</productName>
    <price>100</price>
   </product>
   <product>
    <productName>Test2</productName>
    <price>200</price>
   </product>
  </products>
</auth>

I'm waiting for your help.

I always use System.Xml.Serialization . Is there any resctriction to not to use other libraries rather than NewtonSoft

    static public void Serialize<T>(string filePath, T obj)
    {
        XmlSerializer writer = new XmlSerializer(typeof(T));
        using (System.IO.StreamWriter file = new System.IO.StreamWriter(filePath))
        {
            writer.Serialize(file, obj);
        }
    }

    static public void Deserialize<T>(string filePath, out T obj)
    {
        obj = default(T);
        if (!File.Exists(filePath)) { throw new FileNotFoundException(filePath); }
        XmlSerializer ser = new XmlSerializer(typeof(T));
        using (XmlReader reader = XmlReader.Create(filePath))
        {
            obj = (T)ser.Deserialize(reader);
        }
    }

Try this:

public string Serialize<T>(T obj)
{
    XmlSerializer xsSubmit = new XmlSerializer(typeof(T));
    using (var sww = new StringWriter())
    {
        using (XmlTextWriter writer = new XmlTextWriter(sww) { Formatting = Formatting.Indented })
        {
            xsSubmit.Serialize(writer, obj);
            return sww.ToString();
        }
    }
}
