大二混子用c#实现简单客车售票系统

Console.Title = "简单客车售票系统";
    string[,] zw = new string[9, 4];
 for(int i = 0; i < 9; i++)
{
    for(int k = 0; k < 4; k++)
    {
        zw[i, k] = "{有票}";
    }
}
string s = string.Empty;
while (true)
{
    System.Console.Clear();
    for (int i = 0; i < 9; i++)
    {
        for (int k = 0; k < 4; k++)
        {
            Console.Write(zw[i,k]);
        }
        Console.WriteLine();
    }
    Console.WriteLine("请输入要购买的行号和列号（如0，2）输入q键退出");
    s = Console.ReadLine();
    if (s == "q")
    {
        break;
    }
    string[] s1 = s.Split(',');
    int one = int.Parse(s1[0]);
    int two = int.Parse(s1[1]);
    zw[one, two] = "{已售}";
