                A.ExecuteNonQuery();
 
                da = A.ExecuteReader();
                da.Read();
                sum.Text = da.ToString();

Do not use ExecuteNonQuery when you are executing a query. See the last part of this article on how to use ExecuteScalar to get your results.
Also you are setting the reader itself to the the label's text rather than the reader's results.

so how do i set the reader's result to the label

[r035198x]

Something like

cmd.CommandText = "SELECT COUNT(*) FROM tableName";
 Int32 count = (Int32) cmd.ExecuteScalar();

You then set the value count to be your label's text.
