二维数组循环这个怎么写？

[hsie168518]

int[][] array = new int[9][];

            array[0] = new int[] { 3, 0, 5, 6, 0, 0, 0, 8, 0 };
            array[1] = new int[] { 0, 0, 8, 0, 0, 0, 6, 0, 0 };
            array[2] = new int[] { 0, 7, 0, 0, 0, 1, 0, 5, 0 };

            array[3] = new int[] { 9, 6, 0, 0, 2, 0, 0, 0, 0 };
            array[4] = new int[] { 0, 0, 0, 9, 0, 5, 0, 0, 0 };
            array[5] = new int[] { 0, 0, 0, 0, 4, 0, 0, 3, 9 };

            array[6] = new int[] { 0, 4, 0, 5, 0, 0, 0, 7, 0 };
            array[7] = new int[] { 0, 0, 7, 0, 0, 0, 2, 0, 0 };
            array[8] = new int[] { 0, 1, 0, 0, 0, 7, 3, 0, 4 };

我定义了如上的二维数组。我要找到这些数。

int[] a01=new int[]{2,9};
int[] a04=new int[]{1,7,9};
..
int[] a10=new int[]{1,2,4,5,7};
..
即列行循环，若值为0，就以座标形式定义变量，找出横竖不在1到9中的数字组成数组，全部找出来。

怎么写程序？？

 ArrayList list1 = new ArrayList(new int[] { });

            for (int i = 0; i < array.Length; i++)
            {
                for (int j = 0; j < array[i].Length; j++)
                {
                    if (array[i][j] == 0) result = GetResult(i, j, array);
                    list1.Add(result);
                }

为什么有81行数据？

把重复的数据删除怎么删？为什么我的删不干净？

 list1.Remove("");            
            for(int m=0;m<list1.Count;m++)
                for(int n=m+1;n<list1.Count;n++)
                    if(list1[n]==list1[m])
                    {
                        string tmp=list1[n].ToString();
                        list1.Remove(tmp);
                    }     

[止戈而立]

ArrayList list1 = new ArrayList(new int[] { });

for (int i = 0; i < array.Length; i++)
{
for (int j = 0; j < array[i].Length; j++)
{
if (array[i][j] == 0)
{
result = GetResult(i, j, array);

知道你的意思了。。这样就不会81行了。。

好怪，就少了一个刮号？？

太感谢你了，接分

楼主的数组 并不是二维数组，是锯齿数组。二维数组 是[,]这样。
你的数组好麻烦。
建议用二维数组，再利用2个 for循环，就能得出每一个值。

你这个好象是嵌套数组又叫锯齿数组,好象和多维数组有点区别

先从第一行循环，发现array[0][1]=0,

这里行有 （3568）竖有（7641），在1到9中只是（2,9）没包涵在其中。

所以找到a01="2,9";
