[Data] 后台与前台交互的新新问题

后台cs中：
using System;
using System.Collections;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
using System.Data.SqlClient;
public partial class inquire : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        string Number = Request.Params["number"];
        SqlConnection conn = new SqlConnection("Data Source=LENOVO-2A6446E0;Initial Catalog=jwgl;Integrated Security=True");
        conn.Open();
        string mySel = "select * from allinformation where 学号='" + Number + "'";
        SqlCommand com = new SqlCommand(mySel, (SqlConnection)conn);
        SqlDataReader reader = com.ExecuteReader();
        if (!reader.HasRows)
        {
            Response.Write("{successalse}");
        }
        else
        {
            while (reader.Read())
            {
             
            }
        }
        reader.Close();
        conn.Close();
    }
}

怎样用Response.Write()返回reader里面的值
