C# Serialization between Objects to XML

Question

This is my first attempt at serializing an XML and I need to understand why errors occur in my code:

private void function(Object2 InputParameters)
{

   XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
   ns.Add("", "");
   XmlSerializer s = new XmlSerializer(typeof(Object1));
   StringWriter XMLWriter = new StringWriter();
   s.Serialize(XMLWriter, InputParameters, ns);

   XmlDocument DOC_Xml = new XmlDocument();
   DOC_Xml.LoadXml(XMLWriter.ToString());
}

InnerException:

{"An object of type 'SRV.Entities.Object2' cannot be converted to type 'SRV.Entities.Object1'."}

StackTrace:

"   in System.Xml.Serialization.XmlSerializer.Serialize(XmlWriter xmlWriter, Object o, XmlSerializerNamespaces namespaces, String encodingStyle, String id)\r\n   in System.Xml.Serialization.XmlSerializer.Serialize(TextWriter textWriter, Object o, XmlSerializerNamespaces namespaces)\r\n "

The error line is at s.Serialize(XMLWriter, ParametrosEntrada, ns); but I don't understand the reason. How could I solve the serialization between different objects? Thank you, guys.

Answer 1

You have a bug

private void function(Object2 InputParameters)

and

XmlSerializer s = new XmlSerializer(typeof(Object1));

you need

XmlSerializer s = new XmlSerializer(typeof(Object2));

aka, you need to consistently have "Object2" as the input parameter AND the argument of "typeof".

More deeply, you can consider Generics. So you can pass the type is.... as needed . Either Object1 OR Object2. (but not both)

private void MyFunction<T>(T InputParameters)
{

   XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
   ns.Add("", "");
   XmlSerializer s = new XmlSerializer(typeof(T));
   StringWriter XMLWriter = new StringWriter();
   s.Serialize(XMLWriter, InputParameters, ns);

   XmlDocument DOC_Xml = new XmlDocument();
   DOC_Xml.LoadXml(XMLWriter.ToString());
}
