Serialize object to Xml string

For easy reference, this is how to serialize an object to an Xml string:

public static string SerializeToXmlString<T>(T o)
{
   XmlSerializer serializer = new XmlSerializer(typeof(T));
   StringWriter writer = new StringWriter();
   serializer.Serialize(writer, o);
   writer.Close();
   return writer.GetStringBuilder().ToString();
}
