C# -- 交错数组的使用

交错数组是元素为数组的数组。交错数组元素的维度和大小可以不同。交错数组有时称为“数组的数组”。

1. 举例一：子数组是长度相同的一维数组

static void Main(string[] args)
{
    string[][] week = new string[3][];
    week[0] = new string[] { "星期日", "星期一", "星期二", "星期三", "星期四", "星期五", "星期六" };
    week[1] = new string[] { "周日", "周一", "周二", "周三", "周四", "周五", "周六" };
    week[2] = new string[] { "Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday" };

    for (int i = 0; i < week.Length; i++)
    {
        Console.WriteLine("----------------------------------------------------------------");
        Console.Write("第" + (i + 1).ToString() + "个数组的值：");
        for (int j = 0; j < week[i].Length; j++)
        {
            Console.Write(week[i][j] + ",");
        }
        Console.WriteLine();
    }

    Console.ReadKey();
}

2. 举例二：子数组是长度不同的一维数组

static void Main(string[] args)
{

    int[][] number = new int[3][];
    number[0] = new int[] { 1, 3, 5, 7, 9 };
    number[1] = new int[] { 0, 2, 4, 6, 8 };
    number[2] = new int[] { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 };
    for (int i = 0; i < number.Length; i++)
    {
        Console.WriteLine("----------------------------------------------------------------");
        Console.Write("第" + (i + 1).ToString() + "个数组的值：");
        for (int j = 0; j < number[i].Length; j++)
        {
            Console.Write(number[i][j] + ",");
        }
        Console.WriteLine();
    }

    Console.ReadKey();
}

3. 举例三：子数组是长度不同的二维数组

static void Main(string[] args)
{
    string[][,] numberX = new string[3][,];
    numberX[0] = new string[2, 2] { { "A", "A" }, { "B", "B" } };
    numberX[1] = new string[3, 3] { { "A", "A", "A" }, { "B", "B", "B" }, { "C", "C", "C" } };
    numberX[2] = new string[4, 4] { { "A", "A", "A", "A" }, { "B", "B", "B", "B" }, { "C", "C", "C", "C" }, { "D", "D", "D", "D" } };

    for (int i = 0; i < numberX.Length; i++)
    {
        Console.WriteLine("----------第" + (i + 1).ToString() + "个二维数组--------------------------");
        for (int j = 0; j < Math.Sqrt(numberX[i].Length); j++)
        {
            for (int k = 0; k < Math.Sqrt(numberX[i].Length); k++)
            {
                Console.Write(numberX[i][j, k] + " ");
            }
            Console.WriteLine();
        }
    }

    Console.ReadKey();
}
