C# help please!

Question

Hi I have a little problem with c # code. I wonder if you can help me because I have tried to solve this problem for several days. I get the error: "No overload for method 'ReserveOrCancelSeat' takes '0 'arguments

Here is the code:

private void ReserveOrCancelSeat(SeatManager.DisplayOptions choice)
        {
            if (CheckSelectedIndex() == false)
            {
                MessageBox.Show("a seat must be selected", "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
            }

            // Is reserve selected
            if (rbtnReserve.Checked == true)
            {
                // Validate data
                string name = null;
                double price = 0.0;
                if (ReadAndValidateInput(out name, out price) == true)
                {
                    // Data is ok, reserve seat
                    if (!m_seatMngr.ReserveSeat(name, price, lbSeats.SelectedIndex))
                    {
                        // The seat was already reserved, ask user if we should continue with reservation
                        if (MessageBox.Show("The seat is already reserved, continue with reservation?", "Seat already reserved", MessageBoxButtons.YesNo) == DialogResult.Yes)
                        {
                            // We continue. First cancel seat.
                            if (!m_seatMngr.CancelSeat(lbSeats.SelectedIndex))
                            {
                                // This should not happen, throw exception
                                throw new Exception("The seat could not be canceled.");
                            }
                            // Then we reserve it
                            if (!m_seatMngr.ReserveSeat(name, price, lbSeats.SelectedIndex))
                            {
                                // This should not happen, throw exception
                                throw new Exception("The seat could not be reserved.");

                            }
                        }
                    }
                }

            }
        }

private void btnOK_Click(object sender, EventArgs e)
        {
            ReserveOrCancelSeat(); // here comes the error message
        }

Hey Goran Shoan  sorryyy..... for late reply..... Agree to Vulpes's opinion. But dear friend  you are again doing the same thing. Please don't write word  choice  as it is as shown in example. choice is the object of SeatManager.DisplayOptions DataType so pass the parameter of type SeatManager.DisplayOptions . I think you are using Enum values or Integer Values so pass that VALUES

Vulpes · Answer

If you're using Mayur's approach then you need to pass the method an argument of type SeatManager.DisplayOptions. As it's not a .NET Framework type we don't know what values it has. However it looks to me like it could be an enum so I'd try passing a value of zero: ReserveOrCancelSeat(0);

Mayur Dighe i get a new message The name does not exist in the current context when doing ReserveOrCancelSeat( choice ) ;

Vulpes · Answer

You could also remove the argument from the method as it's not actually used: private void ReserveOrCancelSeat() // now takes no arguments { if (CheckSelectedIndex() == false) // etc }

Hey Goran Shoan  you just make a single Silly Mistake  need to correct it. you can do it but need to just pass the appropriate argument with ReserveOrCancelSeat() Function . i.e. ReserveOrCancelSeat( choice ) ; This will work..... Happy Programming................
