23行的问题，断点调试看看select查询有没有查到数据

你查询出的表里没有记录
所以取值时要判断一下

DataTable dt = Sqlbase.ExecuteTable(CommandType.Text, "select * from book where id=" + Convert.ToInt32(Request["id"]), null);
if(dt.Rows.Count>0)
{
lbname.Text=dt.Rows[0]["name"].ToString();
lbkit.Text = dt.Rows[0]["kit"].ToString();
lborther.Text = dt.Rows[0]["author"].ToString();
}
else
{
lbname.Text="";
lbkit.Text ="";
lborther.Text = "";
}

if(dt.Rows.Count>0)
需要判断阿

立马就解决啦！(*^__^*) 嘻嘻……！谢谢啦！
