How to create generic method to serialize XML string in Class object?

  • 772

I am developing an application where I get XML formatted strings so I have to serialize each string in its respective class.

What I want is to create a single method in which I can serialize these xml-formatted strings into their respective object class, obviously passing as a parameter the type of the class to serialize into.

My code:

public Invoice XML(string xml, out string Error)
    {
        Invoice comprobante = new Invoice();

        Error = "";
        try
        {
            XmlSerializer serializer = new XmlSerializer(typeof(Invoice));
            StringReader sXML = new StringReader(xml);
            comprobante = (Invoice)serializer.Deserialize(sXML);

        }
        catch (Exception ex)
        {
            Error = "Error en la Serialización" + ex.Message;
            comprobante = new Invoice();
        }
        return comprobante;

    }
c#

    Your generic method would look like this:

            public T Xml<T>(string xml, out string Error) where T : new()
        {
            T comprobante = new T();

            Error = "";
            try
            {
                XmlSerializer serializer = new XmlSerializer(typeof(T));
                StringReader sXML = new StringReader(xml);
                comprobante = (T)serializer.Deserialize(sXML);

            }
            catch (Exception ex)
            {
                Error = "Error en la Serialización" + ex.Message;
                comprobante = new T();
            }
            return comprobante;

         }

    You need the new() constraint which indicates that the class must have a default constructor:

    public T Xml<T>(string xml, out string Error) where T : new()
