7in10笔记：.Net中遍历页面中的.NET控件

Control formcontrol = this.FindControl("Form1");
            for(i=0;i<formcontrol.Controls.Count;i++)
            {
                controltype=formcontrol.Controls[i].GetType().Name;
                if(controltype!=null&&controltype=="RadioButtonList")
                {
                    if(((RadioButtonList)formcontrol.Controls[i]).SelectedIndex==-1)
                    {
                        mesbox("请回答所有的问题后再进行提交！");
                        return;
                    }
                    score=score+Convert.ToInt32(((RadioButtonList)formcontrol.Controls[i]).SelectedValue);
                }
            }
