C#组合两个2D字节数组(填充零)

// 定义两个2D字节数组
byte[,] array1 = new byte[3, 3] { { 1, 2, 3 }, { 4, 5, 6 }, { 7, 8, 9 } };
byte[,] array2 = new byte[3, 3] { { 10, 11, 12 }, { 13, 14, 15 }, { 16, 17, 18 } };

// 获取数组的行数和列数
int rows = array1.GetLength(0);
int cols = array1.GetLength(1);

// 创建一个新的2D字节数组用于存储组合后的结果
byte[,] combinedArray = new byte[rows, cols * 2];

// 将array1复制到combinedArray的左侧
for (int i = 0; i < rows; i++)
{
    for (int j = 0; j < cols; j++)
    {
        combinedArray[i, j] = array1[i, j];
    }
}

// 将array2复制到combinedArray的右侧
for (int i = 0; i < rows; i++)
{
    for (int j = 0; j < cols; j++)
    {
        combinedArray[i, j + cols] = array2[i, j];
    }
}

// 输出组合后的结果
for (int i = 0; i < rows; i++)
{
    for (int j = 0; j < cols * 2; j++)
    {
        Console.Write(combinedArray[i, j] + " ");
    }
    Console.WriteLine();
