Question

 string[,] Arr = new string[4, 5]{{"1A" , " 2A" , " 3A" , " 4A" , " 5A"},
    {"1B" , " 2B" , " 3B" , " 4B" , " 5B"},

    {"1D" , " 2D" , " 3D" , " 4D" , " 5D"}};

        Console.WriteLine("List of availabe seats.");
        Console.WriteLine();

        for (int j = 0; j < Arr.Length; j++)

            for (int i = 0; i < Arr.GetLength(0); i++)

如何在程序满时关闭程序？如果我运行这个程序它只结束了20个循环，所以如果我输入两个“2A”，程序将无法完成所有席位，程序将关闭。我是c＃的初学者。

好吧，如果你需要＆＃34;快速和肮脏＆＃34;解决方案然后将您的fullyBooked变量声明移到main for循环之外，并将for循环从for (int j = 0; j < Arr.Length; j++)更改为类似

bool isFullyBooked = false;
while (!isFullyBooked)
{
  // rest of your code, but change bool isFullyBooked = true; 
  // to simply isFullyBooked = true; without declaration, only assignment
  // because it was declared earlier

因此，您的主循环将一直运行，直到所有座位都被预订。

但又一次 - 它非常快速而且肮脏＆＃34;修复，考虑重构您的实现，因为它看起来不是很好。（我想这里有点偏离主题，并受code review）
