How to pass a class to the parameters in a c# method?

Question

C++ / C#

I want to pass a class in the ObjectToXml parameter for further use in the XmlSerializer,
but this is impossible. How can this problem be solved?
ObjectToXml(resp, ResponseZZZ);

[XmlRoot(ElementName = "response")]
    public class ResponseZZZ
    {
        [XmlElement(ElementName = "txn_id")]
        public string txn_id { get; set; }
        [XmlElement(ElementName = "result")]
        public string Result { get; set; }
        [XmlElement(ElementName = "comment")]
        public string Comment { get; set; }
    }

public static XmlDocument ObjectToXml(Object obj, Class MyClass) {// Нельзя передавать Class

        XmlDocument xml = new XmlDocument();

        XmlSerializer formatter = new XmlSerializer(typeof(ResponseZZZ));

        using (MemoryStream memStm = new MemoryStream())
        {
            formatter.Serialize(memStm, obj);

            memStm.Position = 0;

            XmlReaderSettings settings = new XmlReaderSettings();
            settings.IgnoreWhitespace = true;

            using (var xtr = XmlReader.Create(memStm, settings))
            {
                xml = new XmlDocument();
                xml.Load(xtr);
            }
        }

        return xml;
    }

class Program
    {
        static void Main(string[] args)
        {
            ObjectToXml(new object(), new ResponseZZZ());
            Console.ReadLine();
        }

        public static XmlDocument ObjectToXml<SerializationType>(Object obj, SerializationType MyClass) where SerializationType : class, new()
        {
            XmlDocument xml = new XmlDocument();

            XmlSerializer formatter = new XmlSerializer(typeof(SerializationType));

            using (MemoryStream memStm = new MemoryStream())
            {
                formatter.Serialize(memStm, obj);

                memStm.Position = 0;

                XmlReaderSettings settings = new XmlReaderSettings();
                settings.IgnoreWhitespace = true;

                using (var xtr = XmlReader.Create(memStm, settings))
                {
                    xml = new XmlDocument();
                    xml.Load(xtr);
                }
            }

            return xml;
        }

    }


    [XmlRoot(ElementName = "response")]
    public class ResponseZZZ
    {
        [XmlElement(ElementName = "txn_id")]
        public string txn_id { get; set; }
        [XmlElement(ElementName = "result")]
        public string Result { get; set; }
        [XmlElement(ElementName = "comment")]
        public string Comment { get; set; }
    }
