现form下有一tabControl，含有四个TabPages，每个page有含有一个tablelayoutpanel，每个panel含有100个lable，共400个，现在我想用类似controls的方法去遍历这些个lable，该怎么操作呢？？

pannel内查找label可以，
((Label)tableLayoutPanel2.Controls["label" + i.ToString()]).Text

tabpages内查找该怎么操作呢？

foreach (TabPage page in tabControl1.TabPages)
            {
                foreach (Control c in page.Controls)
                {
                    TableLayoutPanel tPanel = c as TableLayoutPanel;
                    if (tPanel != null)
                    {
                        foreach (Control ctl in tPanel.Controls)
                        {
                            Label lab = ctl as Label;
                            if (lab != null)
                            {
                                //lab.Text
                            }
                        }
                    }
                }
            }
