ciao a tutti ho un problema urgente...

nella web.config ho:

<appSettings>
<add key="CnnStr" value="server=.\sqlexpress;uid=SA;pwd=BLACKBOX;dat abase=training"/>
</appSettings>

nel login.aspx.cs:

string connectionString = null;

SqlConnection conn = new SqlConnection();
ConnectionStringSettings settings = WebConfigurationManager.ConnectionStrings["CnnStr"];
if (settings != null)
{
connectionString = settings.ConnectionString;
}
conn.ConnectionString = connectionString;

DataTable getDataTable=new DataTable ();

DataTable ds = null;
SqlDataAdapter adapter = null;
SqlCommand cmd = null;

conn.Open();
string sSQL="SELECT UserName,Password FROM AnagraficaUtenti WHERE UserName='qwerty' and Password='qwerty'";
cmd = new SqlCommand(sSQL, conn);
cmd.CommandType = CommandType.Text;

adapter = new SqlDataAdapter(cmd);
ds = new DataTable();
adapter.Fill(ds);
adapter.Dispose();

la mia domanda e:ma sto leggendo la cnnstr dal web.config??e come faccio??
