C# - Re-using a DataAdapter

Hi guys 'n gals,

I wanted to know if there is a way so consolidate my code, by maybe re-using my DataAdapter variable, rather than creating a new one for each query to the database? Here is how my code looks at the moment:

        void FillDataTables()
        {
            MySqlConnection conn = new MySqlConnection(connString);
            DataSet ds = new DataSet();
            conn.Open();
            MySqlDataAdapter adapter = new MySqlDataAdapter("SELECT * FROM tblConnections", conn);
            adapter.Fill(ds);
            adapter = null;
            MySqlDataAdapter adapter = new MySqlDataAdapter("SELECT * FROM tblInspector", conn);
            adapter.Fill(ds);
            conn.Close();

            MessageBox.Show(ds.Tables.Count.ToString());
        }


It throws the following error:

Error      1      A local variable named 'adapter' is already defined in this scope



Any ideas on getting past this?


Cheers guys!
