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[][];

    week[] = new string[] { "星期日", "星期一", "星期二", "星期三", "星期四", "星期五", "星期六" };

    week[] = new string[] { "周日", "周一", "周二", "周三", "周四", "周五", "周六" };

    week[] = new string[] { "Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday" };

    for (int i = ; i < week.Length; i++)

    {

        Console.WriteLine("----------------------------------------------------------------");

        Console.Write("第" + (i + ).ToString() + "个数组的值：");

        for (int j = ; 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[][];

    number[] = new int[] { , , , ,  };

    number[] = new int[] { , , , ,  };

    number[] = new int[] { , , , , , , , , ,  };

    for (int i = ; i < number.Length; i++)

    {

        Console.WriteLine("----------------------------------------------------------------");

        Console.Write("第" + (i + ).ToString() + "个数组的值：");

        for (int j = ; 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[][,];

    numberX[] = new string[, ] { { "A", "A" }, { "B", "B" } };

    numberX[] = new string[, ] { { "A", "A", "A" }, { "B", "B", "B" }, { "C", "C", "C" } };

    numberX[] = new string[, ] { { "A", "A", "A", "A" }, { "B", "B", "B", "B" }, { "C", "C", "C", "C" }, { "D", "D", "D", "D" } };

    for (int i = ; i < numberX.Length; i++)

    {

        Console.WriteLine("----------第" + (i + ).ToString() + "个二维数组--------------------------");

        for (int j = ; j < Math.Sqrt(numberX[i].Length); j++)

        {

            for (int k = ; k < Math.Sqrt(numberX[i].Length); k++)

            {

                Console.Write(numberX[i][j, k] + " ");

            }

            Console.WriteLine();

        }

    }

    Console.ReadKey();

}
