Question

MSSQL Server could return query result as XML format. My question is, could I use C# to invoke this function directly? I just want to generate XML without using any serialization or some other methods which used in traditional C# codes.

Thanks

You could use ExecuteXmlReader

From here:

   using(SqlConnection cn = new SqlConnection("data source=(local);initial catalog=pubs;.....")) {
        cn.Open();
        SqlCommand cmd = new SqlCommand("SELECT * FROM authors FOR XML AUTO, XMLDATA", cn);

        XmlReader xmlr = cmd.ExecuteXmlReader();
        xmlr.Read();
        while(xmlr.ReadState != ReadState.EndOfFile) {
                    Console.WriteLine(xmlr.ReadOuterXml());
        }                       
   }
