I want to serialize the class ‘kyerocontent’ but only it’s content (kyero and property classes), so on the XML file generated, it doesn’t appear “kyerocontent” as an element.

public async Task<string> GenerateKyeroXml(UserModel user, List<ProductFields> properties)
{
    // Initialize the list to hold individual XML strings for each property
    List<string> kyeroList = new List<string>();

    // Foreach to transform each property to XML
    properties.ForEach(property =>
    {
        // Transform the property to XML
        var propertyobject = new Kyero.property
        {
            id = property?.Id, //verificar?
            reference = GetValueOrNull(property?.Code)?.ToString(),//property61(está sempre null?) ou será name/code?
            currency = GetValueOrNull(property?.PurchasingCurrency),
            date = GetValueOrNull(property.DateCreate?.ToString("yyyy-MM-dd HH:mm:ss")), //verificar
            price = Convert.ToDecimal(GetValueFromDictionary(property.CustomFields, "property70")?.ToString().Split("|")[0]), //verificar o 160000|EUR
            type = GetValueFromDictionary(property.CustomFields, "property60")?.ToString(),//verificar "house" "land" etc...
            province = null, //Algarve
            country = GetValueFromDictionary(property.CustomFields, "property302")?.ToString(),
            price_freq = null, //verificar sale/rent/etc
            town = GetValueFromDictionary(property.CustomFields, "property305")?.ToString(),
            //status = GetValueFromDictionary(property.CustomFields, "property69")?.ToString(),
            beds = ConvertToNullableInt(GetValueFromDictionary(property.CustomFields, "property75")),
            baths = ConvertToNullableInt(GetValueFromDictionary(property.CustomFields, "property76")),
            pool = ConvertYNTo01(GetValueFromDictionary(property.CustomFields, "property79").ToString()), //verificar?
            //images = new List<Kyero.XMLImageUrl>
            //{
            //    new Kyero.XMLImageUrl
            //    {
            //        ID = imageCounter,
            //        url =GetValueFromDictionary(property.CustomFields, "property303")?.ToString(),
            //    },
            //},
            energyrating = new EnergyRating
            {
                consumption = ConvertConsumption(GetValueFromDictionary(property.CustomFields, "property83")?.ToString()),
            },
            surfacearea = new SurfaceArea
            {
                built = ConvertToNullableInt(GetValueFromDictionary(property.CustomFields, "property77")),
                plot = ConvertToNullableInt(GetValueFromDictionary(property.CustomFields, "property78")),
            },
            desc = new XMLDescList
            {
                PT = GetValueFromDictionary(property.CustomFields, "property307")?.ToString(),
                EN = GetValueFromDictionary(property.CustomFields, "property308")?.ToString(),
                FR = GetValueFromDictionary(property.CustomFields, "property309")?.ToString(),
                DE = GetValueFromDictionary(property.CustomFields, "property310")?.ToString(),
                NL = GetValueFromDictionary(property.CustomFields, "property311")?.ToString(),
                SV = GetValueFromDictionary(property.CustomFields, "property312")?.ToString(),
                RU = GetValueFromDictionary(property.CustomFields, "property313")?.ToString(),
            },
            features = new List<string>
        {
            GetValueFromDictionary(property.CustomFields, "property279")?.ToString(),
            GetValueFromDictionary(property.CustomFields, "property280")?.ToString(),
            GetValueFromDictionary(property.CustomFields, "property281")?.ToString(),
            GetValueFromDictionary(property.CustomFields, "property282")?.ToString(),
            GetValueFromDictionary(property.CustomFields, "property283")?.ToString(),
            GetValueFromDictionary(property.CustomFields, "property284")?.ToString(),
            GetValueFromDictionary(property.CustomFields, "property285")?.ToString(),
        }
            .Where(feature => feature != null)
            .ToList(),
        };

        // Serialize the individual property to XML and add it to the list
        string propertyString = SerializeToXml(property);
        kyeroList.Add(propertyString);
    });

    var kyeroobject = new kyero
    {
        feed_version = "3",
    };
    string kyeroString = SerializeToXml(kyeroobject);
    kyeroList.Insert(0, kyeroString);

    // Join all the individual XML strings into one string
    string combinedkyero = string.Join("n", kyeroList);

    // Wrap the combined XML content within a root element
    string kyeroWithRoot = $"<root>{"n" + combinedkyero}n</root>";

    // Write the combined XML string to a file
    string filePath = "KyeroXML.xml";
    await File.WriteAllTextAsync(filePath, kyeroWithRoot);

    // Return the file path
    return filePath;
}

private string SerializeToXml<T>(T obj)
{
    XmlSerializer serializer = new XmlSerializer(typeof(T));
    using (MemoryStream ms = new MemoryStream())
    {
        XmlWriterSettings settings = new XmlWriterSettings
        {
            Indent = true,
            OmitXmlDeclaration = true
        };

        // Create XmlWriter with settings
        using (XmlWriter xmlWriter = XmlWriter.Create(ms, settings))
        {
            // Create XmlSerializerNamespaces and set it to null to avoid serializing namespaces
            XmlSerializerNamespaces namespaces = null;

            // Serialize the object
            serializer.Serialize(xmlWriter, obj, namespaces);
        }

        // Convert the serialized data to string
        return Encoding.UTF8.GetString(ms.ToArray());
    }
}

This is my code. I want to return every strings that it finds me on a list, which in case is this ‘combinedkyero’ but without the ‘kyerocontent’.
