ASP.NET-asp.net 不存在此行/列的数据

Question

OleDbConnection myConn = DB.createDB();

    protected void Page_Load(object sender, EventArgs e)
    {
        if (Request.QueryString["id"].ToString() != "add")
        {
            myConn.Open();
            OleDbCommand RsCommand_GetData = new OleDbCommand("select * from [bin_notes] where [id] =" + Request.QueryString["id"].ToString(), myConn);
            OleDbDataReader DataReader_GetData = RsCommand_GetData.ExecuteReader();

            this.title.Text = DataReader_GetData["title"].ToString();
            this.myEditor.InnerText = DataReader_GetData["content"].ToString();

            DataReader_GetData.Close();
            RsCommand_GetData.Dispose();
            myConn.Close();
        }
    }

Answer 1

if (Request.QueryString["id"].ToString() != "add")
{
myConn.Open();
OleDbCommand RsCommand_GetData = new OleDbCommand("select top 1 id,title,content from [bin_notes] where [id] =" + Request.QueryString["id"].ToString(), myConn);
using (OleDbDataReader DataReader_GetData = RsCommand_GetData.ExecuteReader(CommandBehavior.CloseConnection))
{
if (DataReader_GetData.Read())
{
this.title.Text = DataReader_GetData.GetString(1);//字段顺序一定要写对,0开始
this.myEditor.InnerText = DataReader_GetData.GetString(2);
}
}
RsCommand_GetData.Dispose();
myConn.Close();
}

自己解决了，最后改成了这样！
