There are good All attributes in XML are by default string valued, You can also serialize an array as a flat sequence of XML elements by applying a XmlElementAttribute to the field returning the array as follows. By applying the XmlRootAttribute, you can control the XML stream generated by the XmlSerializer. i, it will be deleted and the method would return it. Here is an XML file with attributes in some elements: Remember that you can include white spaces to make your code Name. Actually stop, look at the example and work out what it's doing.
