Question

I’m trying to generate an XML document like the one below. I tried several solution but when I add the namespace, I have the namespace almost everywhere
like

<FieldB xlmns="">BBBBB</FieldB>

Do you have an idea how to get this ?

<?xml version="1.0" encoding="UTF-8" standalone="true"?>
<value attributeA="A" attributeB="B" xmlns:XXX="http://MyURLA" xmlns="http://MyURLB">
    <FieldA>AAAAA</FieldA>
    <FieldB>BBBBB</FieldB>
    <FieldB>BBBBB</FieldB>
    <status attributeC="C">
        <FieldC>ValueFieldC</FieldC>
    </status>
    <LastUpdate date="2011-02-11T10:00:56.350" login="testing"/>
    <XXX:Infos>
        <XXX:Info>
            <XXX:InfoA>false</XXX:InfoA>
            <XXX:InfoB>false</XXX:InfoB>
        </XXX:Info>
    </XXX:Infos>
</value>

You could use a XNamespace:

public class Program
{
    static void Main()
    {
        XNamespace nsA = "http://MyURLA";
        XNamespace nsB = "http://MyURLB";
        var doc = new XDocument(
            new XDeclaration("1.0", "utf-8", "yes"),
            new XElement(
                nsB + "value",
                new XAttribute(XNamespace.Xmlns + "XXXX", nsA),
                new XAttribute("attributeA", "A"),
                new XAttribute("attributeB", "B"),
                new XElement("FieldA", "AAAA"),
                new XElement("FieldA", "BBBB"),
                new XElement("FieldC", "CCCC"),
                new XElement(
                    "status", 
                    new XAttribute("attributeC", "C"),
                    new XElement("FieldC", "ValueFieldC")
                ),
                new XElement(
                    "LastUpdate", 
                    new XAttribute("date", DateTime.Now), 
                    new XAttribute("login", "testing")
                ),
                new XElement(
                    nsA + "Infos",
                    new XElement(nsA + "InfoA", false),
                    new XElement(nsA + "InfoB", false)
                )
            )
        );
        Console.WriteLine(doc.ToString());
    }
}
