C#如何在循环外使用从字符串更改为循环内的int的变量？

Question

代码：

string[] numbers = new string[2];
for (int i = 0; i < numbers.Length; i++)
{
    numbers[i] = Console.ReadLine();
    if (int.TryParse(numbers[i], out int numberTry) && i == 0)
        Console.WriteLine("That would be a number yes.");

    else if (int.TryParse(numbers[i], out numberTry))
        Console.WriteLine("Lovely work! That is indeed two numbers!");

    else
    {
        Console.Clear();
        Console.WriteLine("That's not a number. I am dissapointed.");
        Console.ReadKey();
        Environment.Exit(0);
    }
}

我的问题是我不能在循环外使用 numbers[] 作为 int，因为它在循环内从字符串转换为 int。我需要能够使用作为 int 的方法发送它以对 numbers[0] 和 numbers[1] 执行操作。 提前致谢！

你可以试试这个。它应该可以工作。

    int[] numbers = new int[2];
    for (int i = 0; i < numbers.Length; i++)
    {
        var number = Console.ReadLine();
        if (int.TryParse(number, out int numberTry) && i == 0)
        {
            Console.WriteLine("That would be a number yes.");
            numbers[i] = numberTry;
        }
        else if (int.TryParse(number, out numberTry))
        {
            Console.WriteLine("Lovely work! That is indeed two numbers!");
            numbers[i] = numberTry;
        }
        else
        {
            Console.Clear();
            Console.WriteLine("That's not a number. I am dissapointed.");
            Console.ReadKey();
            Environment.Exit(0);
        }
    }

    Console.ReadKey();
