Answer 1

                    for (int i = 0; i < sdr.FieldCount; i++)
                    {
                        //读出数据来,   自动生成列标头 
                        ColumnHeader ch = new ColumnHeader();
                        ch.Text = sdr.GetName(i).ToString();
                        this.lvFile.Columns.Add(ch);
                        //循环显示列 
                        ListViewItem lvi = new ListViewItem();
MessageBox.Show(sdr.GetValue(i).ToString());//检查从数据库取值，两个字段都取到值
                        lvi.SubItems[i].Text = sdr.GetValue(i).ToString();//catch显示这行出错
                        this.lvFile.Items.Add(lvi);
                    }=>                    for (int i = 0; i < sdr.FieldCount; i++)
                    {
                        //读出数据来,   自动生成列标头 
                        ColumnHeader ch = new ColumnHeader();
                        ch.Text = sdr.GetName(i).ToString();
                        this.lvFile.Columns.Add(ch);
                    }
                    while (sdr.read())
                    {
                    for (int i = 0; i < sdr.FieldCount; i++)
                    {
                        //循环显示列 
                        ListViewItem lvi = new ListViewItem();
MessageBox.Show(sdr.GetValue(i).ToString());//检查从数据库取值，两个字段都取到值
                        lvi.SubItems[i].Text = sdr[i].ToString();//catch显示这行出错
                        this.lvFile.Items.Add(lvi);
                    }
                    }

Answer 2

按照1楼的改后，还是出现同样的错误，指示在lv.Subitems[i].Text = sdr[i].ToString

Answer 3

lvi.SubItems[i].Text 的问题？

Answer 4

是的，就是lvi.SubItems[i].text这个i赋什么值都不行，不管是0还是1
