Serialize objects with no xml decoration and no namespaces

I posted couple of blogs earlier that shows how to Serialize/Deserialize objects and serialize using SOAP formatter. Few times we would like to serialize just the pure xml part of the object with no namespaces and/or no xml declaration tag at the top. Take a look, here's how we can do it in memory (without writing to a file):

/// <summary>
/// Serializes object with no namespace and no <?xml ... > tag. Returns pure xml of the object
/// </summary>
/// <param name="obj"></param>
/// <returns></returns>
internal string SerializeObjectPureXML(Object obj)
{
    string serialXML = "";

    //Empty namespace
    XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
    ns.Add("", "");
    //Serialize the passed object
    XmlSerializer xs = new XmlSerializer(obj.GetType());
    StringBuilder sb = new StringBuilder();
    using (StringWriter sw = new StringWriter(sb))
    {
        // set XML writer settings
        XmlWriterSettings xwSettings = new XmlWriterSettings();
        xwSettings.OmitXmlDeclaration = true;
        xwSettings.Indent = true;
        xwSettings.CloseOutput = true;
        // create xml using the settings
        using (XmlWriter xw = XmlWriter.Create(sw, xwSettings))
        {
            xs.Serialize(xw, obj, ns);
            // get the xml and clean up
            serialXML = sb.ToString();
            xw.Flush();
        }
        sw.Flush();
    }
    //
    return serialXML;
}

Love coding!
