Include Default XML namespace

Question

Srs(as), good morning,

I am generating an XML from the serialization of a class.Cs(schema) and the output is created xml (first example)

.

This will be exported to an external system, however they asked to leave the XML equal to (second example).

From what I’ve seen, there’s a Namespace Defaut (tns) that I would need to include, but I can’t do it.

XML is being generated by the code below.

entitiesList = new extEntitiesList() { entity = tEntity };
                    fileName = string.Format("{0}{1}{2}", sPath, tEntity.idExt, ".xml");
                    serializer = new System.Xml.Serialization.XmlSerializer(typeof(extEntitiesList));                   

                    using (System.IO.StreamWriter sw = new System.IO.StreamWriter(fileName, false, encoding))
                    {
                        serializer.Serialize(sw, entitiesList);
                        //sw.Write(xml.InnerXml);
                        sw.Dispose();
                    }

The class was generated by the XSD.exe VS2010 command. spawned:

[System.CodeDom.Compiler.GeneratedCodeAttribute("xsd", "4.0.30319.1")]
[System.SerializableAttribute()]
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType=true, Namespace="http://value.com/model/v2/")]
[System.Xml.Serialization.XmlRootAttribute(Namespace="http://value.com/model/v2/", IsNullable=false)]

(first example)

    <?xml version="1.0" encoding="iso-8859-1"?>
<extEntitiesList xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://value.com/model/v2/">

Luiz,

Try using Xmlserializernamespaces before serialization:

XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
ns.Add("tns", "http://value.com");
XmlSerializer serializer = new XmlSerializer(typeof(extEntitiesList));
serializer.Serialize(Console.Out, new extEntitiesList(), ns);
