Here's a way to call the seat color update updateseat (), initialize the color of the seats collection and labels collection first, that is, reset the color to yellow, and then set the color of the sold seats to red based on the information sold

1 //Resets the color of the Labels collection label2             foreach(stringLkeyinchlabels. Keys)3             {4Labels[lkey]. BackColor =Color.yellow;5             }6             //Reset seat Set color7             foreach(stringKeyinchCinema. Seats.keys)8             {9Cinema. Seats[key]. Color =Color.yellow;Ten             } One             //traverse the collection of sold tickets A             foreach(Ticket TicketinchCinema. Soldtickets) -             { -                 //if the matches are the same, and the movie names match the                 if(Ticket. Scheduitem.time = = This. TreeView1.SelectedNode.Text && Ticket. ScheduItem.Movie.MovieName = = This. Lblname.text) -                 { -                     //Change color again -Labels[ticket. Seat.seatnum]. BackColor =color.red; +Cinema. Seats[ticket. Seat.seatnum]. Color =color.red; -                 } +}

updateseat ()
