循环遍历listview 控件中Subitems 值

I was wanting to be able to iterate through each of my ListViews sub items and get the value from each. I have tried various things but am finding it really difficult to just get the sub item text from the second column, not the items text from the first column. Thanks.

foreach (ListViewItem itemRow in listView1.Items)
{
    for (int i = 0; i < itemRow.SubItems.Count; i++)
    {
        string dueDate = itemRow.SubItems[i].Text;
        MessageBox.Show(dueDate);
    }
}
