老师您好：
明日科技在线考试页面自定义方法getcom(1),getcom(2),getcom(3),getcom(4),getcom(5)在这个页面中分别起什么作用？我是一个初学者对自定义方法不多理解，请老师指点一下
代码如下：
   if (!IsPostBack)
        {
            this.getCom(1);
            this.getCom(2);
        }


 Label3.Visible = Label4.Visible = Label7.Visible = Label8.Visible = Label9.Visible = Label10.Visible = true;
            this.lblStuID.Text = Session["StuName"].ToString();
            this.lblSubject.Text = Session["SelLession"].ToString();
            this.lblQuestion.Text = Session["SelTitle"].ToString();
            this.getCom(3);
            this.getCom(4);
            this.lblTotal.Text = Convert.ToString(int_row1Point + int_row2Point);
            dataconn.eccom("insert into tb_StuResult"
                     + "(stu_id,which_lesson,taotiid,taotiname,res_single,res_more)"
                     + "values('" + lblStuID.Text + "','" + lblSubject.Text + "',"
                     + Application["d2"].ToString() + ",'" + lblQuestion.Text + "'," + int_row1Point + "," + int_row2Point + ")");
            this.getCom(5);
            Response.Write("<script lanuage=javascript>alert('您确定要交卷吗？');localtion='StartExamfra.aspx';</script>");
