一个给多选题判分的代码，老是只判一道题，看不出错误。

Question

//核对多选题答案
            case 4:
                SqlDataAdapter myadapter4 = new SqlDataAdapter("select id,que_answer"
                    + " from tb_Questions where que_type='多选题'and que_lessonid='"
                    + dd1 + "'and que_taotiid='" + dd2 + "'order by id desc", con);
                DataSet myds4 = new DataSet();
                myadapter4.Fill(myds4);
                DataRow[] row2 = myds4.Tables[0].Select();
                //计算多选题成绩
                foreach (DataRow answer2 in row2)
                {
                    int_row2 += 1;
                   if (introw2 <= DataList2.Items.Count)
                   {
                    CheckBoxList cbl = (CheckBoxList)(DataList2.Items[int_row2 - 1].FindControl("CheckBoxList1"));
                    if (cbl.SelectedValue == "")
                    {
                        lblDSel.Text = "多选题：0分";
                    }
                    else
                    {
                        for (int q = 0; q < cbl.Items.Count; q++)
                        {
                            if (cbl.Items[q].Selected == true)
                            {
                                this.TextBox1.Text = TextBox1.Text.Trim() + cbl.Items[q].Value + ", ";
                            }
                        }
                        if (answer2["que_answer"].ToString().Trim() + "," == this.TextBox1.Text.Trim())
                        {
                            int_row2Point += 60 / DataList2.Items.Count;
                            this.lblDSel.Text = "多选题：" + int_row2Point.ToString() + "分";
                        }
                    }
                  ｝
                }
                break;

Answer 1

单步调试看看int_row2 值
foreacg(DatalistItem item in DataList2.Items){}

Answer 2

找到问题了，
 if (answer2["que_answer"].ToString().Trim() + "," == this.TextBox1.Text.Trim())
  {
  int_row2Point += 60 / DataList2.Items.Count;
  this.lblDSel.Text = "多选题：" + int_row2Point.ToString() + "分";
  }
在这后面加一句清空变量的语句： this.TextBox1.Text=“”；
