How to set xmlns when serializing object in c#

Question

I am serializing an object in my ASP.net MVC program to an xml string like this;

StringWriter sw = new StringWriter();
XmlSerializer s = new XmlSerializer(typeof(mytype));
s.Serialize(sw, myData);

Now this give me this as the first 2 lines;

<?xml version="1.0" encoding="utf-16"?>
<GetCustomerName xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

my question is, How can I change the xmlns and the encoding type, when serializing?

Thanks

What I found that works was to add this line to my class,

[System.Xml.Serialization.XmlRootAttribute(Namespace = "http://myurl.com/api/v1.0", IsNullable = true)]

and add this to my code to add namespace when I call serialize

    XmlSerializerNamespaces ns1 = new XmlSerializerNamespaces();
    ns1.Add("", "http://myurl.com/api/v1.0");
    xs.Serialize(xmlTextWriter, FormData, ns1);

as long as both namespaces match it works well.
