bbs与repeater。第几楼？repeater中绑定的数据显示第几条，翻页后可以继续！

protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
string sql = "";
sql = "SELECT * FROM dtproblem order by rand()";
DataTable dt = DTEDb.GetDataTable(sql);
//加入题数。为DataTable加入新列“NewNum”记录数目
dt.Columns.Add("NewNum", typeof(int));
int i = 0;
foreach (DataRow row in dt.Rows)
{
i++;
row["NewNum"] = i.ToString();
}
dt.Dispose();
}
}
