hello.
my last problem about connecting to SQL was solved
is the code below correct for a query?

Code:
string conStr = "Data Source=.;Initial Catalog=WSD;Integrated Security=True";                                                      //connection string
SqlConnection conn = new SqlConnection(conStr);
conn.Open();
string query = "select * from [P_E_wsd] where (english='network')";                                            //query
DataSet ds = new DataSet();
SqlDataAdapter da = new SqlDataAdapter();
da.SelectCommand = new SqlCommand(query, conn);
da.Fill(ds, "P_E_wsd") ;          
DataTable dt = ds.Tables[0];
conn.Close();
how can I access to the result of the query?
I know the answer should be in 'dt' but after the code is run I see non of the entry of the table in 'dt'(I check it in locals) while if I use that query command in SQL the answer will be a table with 2 rows and 4 columns.

thank you
