How to serialize an c# object into xml without schema info? [duplicate]

Answer 1

You need a few xml tricks...

var serializer = new XmlSerializer(typeof(List));

var ns = new XmlSerializerNamespaces();
ns.Add("", "");
var sw = new StringWriter();
var xmlWriter = XmlWriter.Create(sw, new XmlWriterSettings() { OmitXmlDeclaration = true });

serializer.Serialize(xmlWriter, model, ns);
string xml = sw.ToString(); 

Output:

  
    a
    1
  
  
    b
    2
  

PS: I added Indent = true to XmlWriterSettings to get the above output
