How about you just save the xml to a file  and use xsd to generate C  classes    Write the file to disk  I named it foo xml  Generate the xsd  xsd foo xml Generate the C   xsd foo xsd  classes   Et voila - and C  code file that should be able to read the data via XmlSerializer       XmlSerializer ser   new XmlSerializer typeof Cars        Cars cars      using  XmlReader reader   XmlReader Create path                 cars    Cars  ser Deserialize reader            include the generated foo cs in the project

I don t think  net is  picky about deserializing arrays   The first xml document is not well formed  There is no root element  although it looks like there is  The canonical xml document has a root and at least 1 element  if at all   In your example    lt Root gt   lt -- well  the root    lt Cars gt   lt -- an element  not a root   it being an array      lt Car gt   lt -- an element  it being an array item              lt  Car gt     lt  Cars gt   lt  Root gt

I don t think  net is  picky about deserializing arrays   The first xml document is not well formed  There is no root element  although it looks like there is  The canonical xml document has a root and at least 1 element  if at all   In your example    lt Root gt   lt -- well  the root    lt Cars gt   lt -- an element  not a root   it being an array      lt Car gt   lt -- an element  it being an array item              lt  Car gt     lt  Cars gt   lt  Root gt
