Xmlwriter creates XML files my code

1. Use two writer. writestartelement ("") // to achieve the sub-node effect

static void main (string [] ARGs)
{< br> string app_path = application. startuppath + "\ gouwuke. XML ";
xmlwritersettings settings = new xmlwritersettings ();
Settings. indent = true;
Settings. indentchars = ("");
using (xmlwriter writer = xmlwriter. create (app_path, settings)
{< br>

// Write a comment node.
Writer. writecomment ("this is a comment"); // comment

Writer. writestartelement ("book ");
// Writer. writeattributestring ("genre", "novel"); Attribute
// Writer. writeattributestring ("ISBN", "1-8630-014"); Attribute

Sqlconnection con = new sqlconnection (@ "Server = 172.16.10.80; database = gouwuke_chs; uid = admin; Pwd = 7418 ;");
Sqldataadapter SDA = new sqldataadapter ("select Ident, productname from gwkproduct where ident like 'piaoliang100% '", con );
Dataset DS = new dataset ();
SDA. Fill (DS );
For (INT I = 0; I <Ds. Tables [0]. Rows. Count; I ++)
{
Writer. writestartelement ("chanpin"); // subnode Effect
Writer. writeelementstring ("ident", DS. Tables [0]. Rows [I] ["ident"]. tostring ());
Writer. writeelementstring ("productname", DS. Tables [0]. Rows [I] ["productname"]. tostring ());
Writer. writeendelement ();
}
Writer. writeenddocument ();
Writer. Flush ();
Writer. Close ();

}
