Write xmlns element with attributes

Question

I'm using XmlWriter to generate an XML file. I am trying to replicate an old XML file and I want to create an entry that will look like;

<Return xmlns="http://address/here" appName="Data Return - Collection Tool" appVer="1.1.0">

My code is as follows:

        writer.WriteStartElement("Return", "http://address/here")
        writer.WriteAttributeString("appName", "Data Return - Collection Tool")
        writer.WriteAttributeString("appVer", "1.1.0")

This is generating the attributes in the wrong order ie.

<Return appName="Data Return - Collection Tool" appVer="1.1.0" xmlns="http://address/here">

How can i get these to appear in the order i want. Any help please.

XmlWriter allow you to write the xmlns attribute when you want if the value is the same than the one specified in WriteStartElement :

void Main()
{
    StringWriter stringWriter = new StringWriter();
    using(XmlWriter writer = XmlWriter.Create(stringWriter))
    {
        writer.WriteStartDocument();
        writer.WriteStartElement("Return", "http://address/here");
        writer.WriteAttributeString("xmlns", "http://address/here");
        writer.WriteAttributeString("appName", "Data Return - Collection Tool");
        writer.WriteAttributeString("appVer", "1.1.0");
        writer.WriteEndElement();
        writer.WriteEndDocument();
    }

    Console.WriteLine(stringWriter.ToString());
}

Output :

<Return xmlns="http://address/here" appName="Data Return - Collection Tool" appVer="1.1.0" />
