I have ArrayList of ArrayLists, how can I display the values of each ArrayList. For example if I have arraylist a that contain arraylists (b,c,d), how can I read the values of ArrayLists b, and c and d.

推荐答案

你所要做的就是遍历你的ArrayList，然后遍历你正在循环的ArrayList :)

All you have to do is loop through your ArrayList and then loop through your ArrayList that you're looping through :)

ArrayList arr = new ArrayList();
arr.Add(new ArrayList(new[] { "value 1.1", "value 1.2" }));
arr.Add(new ArrayList(new[] { "value 2.1", "value 2.2" }));
arr.Add(new ArrayList(new[] { "value 3.1", "value 3.2" }));
foreach (ArrayList innerArr in arr)
{
	foreach (object element in innerArr)
	{
		// Do something with the elements.
	}
}

我建议你看一下列表< T> [ ^ ]类虽然？

May I suggest you take a look at the List<T>[^] class though?
