Accepted answer
try like this

string seatNo = pictureBox.Name.Replace("picturebox_", string.Empty);
string seatNo = seatNo.Replace("a", string.Empty);
string seatNo = seatNo.Replace("k", string.Empty);

declare one global variable say (_availableSeat) and assign the total no of seat in default constructor.

private int _availableSeat;

public Form9()
{

InitializeComponent();
_availableSeat = 10; //i take total 10 seat
//here if already seat was booked earlier, then assign
_availableSeat=10 - _totalNoOfBookedSeat
}

Then whenever you book the seat (on the picture box click) decrease the number by 1
_availableSeat--;

private void pictureBox1_Click(object sender, EventArgs e)
{
if (_totalNoOfSeat!=0 && _counter == _totalNoOfSeat)
{
MessageBox.Show("You have selected all seats");
}
else
{
PictureBox pictureBox = (PictureBox)sender;
string seatNo = pictureBox.Name.Replace("pictureBox", string.Empty);
if (_currentSeatNo == 0)
{
_counter++;
_availableSeat--;
_currentSeatNo = Convert.ToInt32(seatNo);
_nextSeatNo = _currentSeatNo + 1;
pictureBox.BackColor = Color.Green;
}
else
{
_counter = _counter + 1;
int tempSeatNo = Convert.ToInt32(seatNo);
if (tempSeatNo == _nextSeatNo)
{
pictureBox.BackColor = Color.Green;
_nextSeatNo = _nextSeatNo + 1;
_availableSeat--;
}
else
{
MessageBox.Show("Please select only sequence seat");
}
}
}
if (_availableSeat == 0)
{
foreach (var pb in this.Controls.OfType())
{
pb.BackColor = Color.Red;
pb.Enabled = false;
}
}
}
