如何在C#中找到arraylist是单维还是多维的？

ArrayList myArrayList = new ArrayList();

// 添加元素到ArrayList
myArrayList.Add(1);
myArrayList.Add(2);
myArrayList.Add(3);

// 检查ArrayList是否是单维的
bool isSingleDimensional = true;

foreach (object item in myArrayList)
{
    if (item is ArrayList)
    {
        isSingleDimensional = false;
        break;
    }
}

if (isSingleDimensional)
{
    Console.WriteLine("This ArrayList is single-dimensional.");
}
else
{
    Console.WriteLine("This ArrayList is multi-dimensional.");
}
