如何遍历维数和各维上限未定的多维数组

static void ArrEnum(Array arr, Action<Int32[]> func)
{
Int32[] ix = new Int32[arr.Rank];
Int32 rank = 0;

for (int i = 0; i < arr.Length; i++)
{
// 当前层以下都清零
for (int j = rank + 1; j < arr.Rank; j++)
{
ix[j] = 0;
}

// 设置为最底层
rank = arr.Rank - 1;

//do something
//arr.SetValue(i, ix);
func(ix);

// 当前层递加
ix[rank]++;

// 如果超过上限，则减少层次
while (ix[rank] >= arr.GetLength(rank))
{
rank--;
if (rank < 0) break;
ix[rank]++;
}
}
}

static void Test2()
{
Int32[, , ,] arr = new Int32[24, 24, 24, 24];

Int32 n=1;
ArrEnum(arr, ix => arr.SetValue(n++, ix));
ArrEnum(arr, delegate(Int32[] ix)
{
Console.Write("[");
for (int i = 0; i < ix.Length; i++)
{
if (i > 0) Console.Write(", ");
Console.Write(ix[i]);
}
Console.Write("]\t");
Console.WriteLine(arr.GetValue(ix));
});
}
