用C#给长度为4、4、3的三维数组第一行赋值

代码如下：

int[,,] array3D = new int[4, 4, 3];

for (int i = 0; i < 4; i++)
{
    for (int j = 0; j < 4; j++)
    {
        for (int k = 0; k < 3; k++)
        {
            if (i == 0)
            {
                array3D[i, j, k] = 1; //第一行赋值为1
            }
            else
            {
                array3D[i, j, k] = 0; //其他行赋值为0
            }
        }
    }
}

//打印数组
for (int i = 0; i < 4; i++)
{
    for (int j = 0; j < 4; j++)
    {
        for (int k = 0; k < 3; k++)
        {
            Console.Write(array3D[i, j, k] + " ");
        }
        Console.WriteLine();
    }
    Console.WriteLine();
}

输出结果：

1 1 1
