c# 代码：System.IndexOutOfRangeException：'索引超出了数组的范围。'请看我的代码[重复]

Question

这些代码没有运行。当我在嵌套循环中尝试在 totalMembers[j] 数组索引上分配整数值时，编译器会抛出提到的异常。请帮助以便该程序可以运行。

        int totalHours = 0, memArraySize = 0;
        int[] totalMembers = new int[memArraySize];
        int[] memHours = new int[memArraySize];
        for (int i = 0; i < 2; i++)
        {
            var stringNumbers = Console.ReadLine();
            var numbers = stringNumbers.Split(' ');
            int.TryParse(numbers[0], out totalHours);
            int.TryParse(numbers[1], out memArraySize);

            for (int j = 0; j < 2; j++)
            {
                totalMembers[j] = Convert.ToInt32(Console.ReadLine());
                memHours[i] = memHours[i] + totalMembers[j];
            }

        }

    int totalHours, memArraySize;
    int[] totalMembers;
    int[] memHours;
    for (int i = 0; i < 2; i++)
    {
        var stringNumbers = Console.ReadLine();
        var numbers = stringNumbers.Split(' ');
        int.TryParse(numbers[0], out totalHours);
        int.TryParse(numbers[1], out memArraySize);
        totalMembers = new int[memArraySize];
        memHours = new int[memArraySize];
        for (int j = 0; j < 2; j++)
        {
            totalMembers[j] = Convert.ToInt32(Console.ReadLine());
            memHours[i] = memHours[i] + totalMembers[j];
        }

    }

以便数组 totalMembers 和 memHours 可以包含值。
