c# - 数组问题(无法将类型 'int' 隐式转换为 'int[]')

Question

我整晚都在寻找一个存储系统的修复程序，用于从一个循环到 3 个循环的限制的用户输入。我相信我已经找到了它，但是正如标题所说，我在用户输入的 console.readline 上收到错误 Cannot implicitly Convert Type 'int' to 'int[]'？关于如何解决这个问题的任何建议？

提前谢谢你。

            //Array For Ticket prices, sales and user input
            int[] TicketChoices = new int[3];

            //Ticket Types
            //ChildT = £1.50 = Child;
            //AdultT = £2.35 = Adult;
            //StudentT = £1.99 = Student;

            //Film      Certificate     Seats   Screen
            //Jaws          12A          15       1
            //The Exorcist  18           33       2

            cw("Hello Current tickets are:");

            for (int I = 0; I < 3; I++)

                {
                    cw("ID (1) Child, £1.50");
                    cw("ID:(2) Adult, £2,35");
                    cw("ID:(3) Student £1.99");
                    cw("");
                    cw("Please Select Which ticket you would like to input By Entering it's id Number");
                    cw("input Must be between 1-3 for it to be vaild.");
                    TicketChoices = int.Parse(Console.ReadLine());

                }

这是我认为您正在尝试做的:

    static void Main()
    {
        //Array For Ticket prices, sales and user input
        var ticketChoices = new int[3];

        //Ticket Types
        //ChildT = £1.50 = Child;
        //AdultT = £2.35 = Adult;
        //StudentT = £1.99 = Student;

        //Film      Certificate     Seats   Screen
        //Jaws          12A          15       1
        //The Exorcist  18           33       2

        Console.WriteLine("Hello Current tickets are:");

        for (var i = 0; i < 3; i++)

        {
            Console.WriteLine("ID (1) Child, £1.50");
            Console.WriteLine("ID:(2) Adult, £2,35");
            Console.WriteLine("ID:(3) Student £1.99");
            Console.WriteLine("");
            Console.WriteLine("Please Select Which ticket you would like to input By Entering it's id Number");
            Console.WriteLine("input Must be between 1-3 for it to be vaild.");
            var valid = false;
            while (!valid)
            {
                var input = Console.ReadLine();
                if (int.TryParse(input, out var ticketNumber))
                {
                    if (ticketNumber >= 0 && ticketNumber <= 3)
                    {
                        valid = true; 
                    }
                }

                if (valid)
                {
                    ticketChoices[i] = ticketNumber;
                }
                else
                {
                    Console.WriteLine("Please enter a value between 1 and 3");
                }
            }
        }

        // Print the results 
        Console.WriteLine("You entered:");
        foreach (var ticketChoice in ticketChoices)
        {
            Console.WriteLine(ticketChoice);
        }

        Console.ReadLine();
    }
