1 通用代码：

    public static ArrayList BtnList(System.Web.UI.Control page)
    ...{
        int nPageControls = page.Controls.Count;

        ArrayList btnText = new ArrayList();
        for (int i = 0; i < nPageControls; i++)
        ...{
            foreach (System.Web.UI.Control control in page.Controls[i].Controls)
            ...{
                if (control is Button)
                ...{
                    //btnText.Add(control.ID);
                    btnText.Add((control as Button).Text);
                }
            }
        }

        return btnText;
    }
　　2 页面调用代码

    protected void Page_Load(object sender, EventArgs e)
    ...{
        ArrayList arrayList = new ArrayList();
        System.Web.UI.Page page1 = (System.Web.UI.Page)HttpContext.Current.Handler;
        arrayList = BtnCtrList.BtnList(page1);

        foreach (object o in arrayList)
        ...{
            ListBox1.Items.Add(o.ToString());
        }
    }
