c# - 在 C# 中按下一个和上一个时如何从数据表中获取 10 条记录？

Question

数据表代码

            OleDbConnection connection = new OleDbConnection(connectionString);
            connection.Open();
            OleDbCommand comand = new OleDbCommand("Select id, name From menu where KlassID=@KlassID", connection);
            comand.Parameters.Add("@KlassID", OleDbType.Integer).Value = KlassID;
            OleDbDataAdapter da = new OleDbDataAdapter(comand);
            DataTable dt = new DataTable();

            da.Fill(dt);

按钮下一步

private void btNext_Click(object sender, EventArgs e) { //enter code here }

按钮上一个

private void btPrevious_Click(object sender, EventArgs e) { //enter code here }

我找到了类似的代码，但这里有一条记录
