是否可以将一维数组复制到描述的二维数组，如果可以，如何复制?

Question

下面的例子是用c#在XNA中从Texture2D提取数据。我的理解是Texture2D。GetData最初不能用于将数据拉入2D数组。

如果一个1D数组包含如下值:1, 2, 3, 4, 5, 6, 7, 8, 9

是否有可能将这个一维数组复制到一个二维数组中，然后这个二维数组的值如下:

1, 2, 3
4, 5, 6
7, 8, 9

我的目标是将整个数组从1D复制到2D，而不是迭代和计算索引。我当前的代码是这样的:

    Color[,] TextureDataTo2DArray(Texture2D texture)
    {
        Color[] colors1D = new Color[texture.Width * texture.Height];
        texture.GetData(colors1D);
        Color[,] colors2D = new Color[texture.Width, texture.Height];
        for (int x = 0; x < texture.Width; x++)
            for (int y = 0; y < texture.Height; y++)
                colors2D[x, y] = colors1D[x + y * texture.Width];
        return colors2D;
    }

在将一维数组复制到二维数组时，模运算是您的朋友:

Color[,] TextureDataTo2DArray(Texture2D texture)
    {
        Color[] colors1D = new Color[texture.Width * texture.Height];
        texture.GetData(colors1D);
        Color[,] colors2D = new Color[texture.Width, texture.Height];
        for (int i = 0; i < colors1D.Length; i++)
            colors2D[Math.Floor(i / texture.Width), i % texture.Width] = colors1D[i];
        return colors2D;
    }

最终，如果你要重塑一个数组，你将不得不计算一个形状和另一个形状之间的对应关系。

你可以增加一个计数器

index = 0;
for (int x = 0; x < texture.Width; x++)
    for (int y = 0; y < texture.Height; y++)
        colors2D[x, y] = colors1D[index++];

        static void Main(string[] args)
        {
            int Size_of_OneDimensional = 0;
            int Start_Index = 0;
            int row = 0;
            int column=0;

            Console.WriteLine("Enter The number of elements you want to add in 1-D Array : ");
            Size_of_OneDimensional = Convert.ToInt32(Console.ReadLine());
            int[] One_Dimensional = new int[Size_of_OneDimensional];
                for (int i = 0; i < Size_of_OneDimensional; i++)
                    {
                        Console.WriteLine("Enter "+i+" Element");
                        One_Dimensional[i] = Convert.ToInt32(Console.ReadLine());
                    }
                Console.WriteLine("Emter Number of Row : ");
                row = Convert.ToInt32(Console.ReadLine());
                Console.WriteLine("Emter Number of Colum : ");
                column= Convert.ToInt32(Console.ReadLine());
                int[,] Two_Dimensional = new int[row, column];
                Console.WriteLine("Here is your 2-D Array");
                for (int i = 0; i < row; i++)
                    {
                    if (Start_Index == One_Dimensional.Length)
                        break;
                    for(int j = 0; j < column; j++)
                        {
                        Two_Dimensional[i, j] = One_Dimensional[Start_Index];
                        Start_Index++;     
                        Console.Write(Two_Dimensional[i, j]);
                        }
                        Console.WriteLine();
                    }
                Console.ReadKey();
        }
    }
   }
