c#实现二维数组转置及二维数组列表List<>转置

class Program
{
    public static string[,] Rotate(string[,] array)
    {
        int x = array.GetUpperBound(0); //一维 
        int y = array.GetUpperBound(1); //二维 
        string[,] newArray = new string[y   1, x   1]; //构造转置二维数组
        for (int i = 0; i <= x; i  )
        {
            for (int j = 0; j <= y; j  )
            { 
                newArray[j, i] = array[i, j]; 
            }
        } 
        return newArray;
    }

    static void Main(string[] args)
    {

        string[,] array = new string[4, 2];
        for (int i = 0; i < 4; i  )
        {
            for (int j = 0; j < 2; j  )
            {
                array[i, j] = i.ToString()   j.ToString();
            }
        }

        //显示原数组
        Console.WriteLine("Source Array:");
        for (int i = 0; i < 4; i  )
        {
            string soureResult = string.Empty;
            for (int j = 0; j < 2; j  )
            {
                soureResult  = array[i, j]   "  ";
            }
            Console.WriteLine(soureResult);
        }

        string[,] newArray = Rotate(array);
        //显示转置后的数组
        Console.WriteLine("Destiney Array:");
        for (int i = 0; i < 2; i  )
        {
            string dstResult = string.Empty;
            for (int j = 0; j < 4; j  )
            {
                dstResult  = newArray[i, j]   "  ";
            }
            Console.WriteLine(dstResult);
        }

        Console.ReadLine();
    }
}

好了，下面接着看二维数组列表List<>的转置
