Answer 1

我明白了!......呵呵

protected DataTable RetrieveEmployeeSubInfo(string employeeNo)
        {
            SqlCommand cmd = new SqlCommand();
            SqlDataAdapter da = new SqlDataAdapter();
            DataTable dt = new DataTable();
            try
            {
                cmd = new SqlCommand("RETRIEVE_EMPLOYEE", pl.ConnOpen());
                cmd.Parameters.Add(new SqlParameter("@EMPLOYEENO", employeeNo));
                cmd.CommandType = CommandType.StoredProcedure;
                da.SelectCommand = cmd;
                da.Fill(dt);
                dataGridView1.DataSource = dt;
            }
            catch (Exception x)
            {
                MessageBox.Show(x.GetBaseException().ToString(), "Error",
                        MessageBoxButtons.OK, MessageBoxIcon.Error);
            }
            finally
            {
                cmd.Dispose();
                pl.MySQLConn.Close();
            }
            return dt;
        }

Answer 2

 SqlConnection con = new SqlConnection(@"Some Connection String");
 SqlDataAdapter da = new SqlDataAdapter("ParaEmp_Select",con);
            da.SelectCommand.CommandType = CommandType.StoredProcedure;
            da.SelectCommand.Parameters.Add("@Contactid", SqlDbType.Int).Value = 123;
            DataTable dt = new DataTable();
            da.Fill(dt);
            dataGridView1.DataSource = dt;
