返回值为对象，调用对象的值为什么和预期的不对
帮帮忙各位大虾们，我在类中定义了一个函数
  public static AAcademe Find_Zys(string username)
  {
  string SqlConnStr = "";
  AAcademe aca = new AAcademe();
  SqlConnStr = AAcademe.Link_Sql_Aca();
  string mysql = "select * from TStudent where login= '" + username + "'";
  SqlConnection myconnection = new SqlConnection(SqlConnStr);
  SqlCommand mycommand = new SqlCommand(mysql, myconnection);
  myconnection.Open();
  SqlDataReader sqlreader = mycommand.ExecuteReader();
  while (sqlreader.Read())
  {
   
  aca.id = int.Parse(sqlreader["id"].ToString());
  aca.academe = sqlreader["academe"].ToString();
  aca.login = sqlreader["login"].ToString();
  aca.pwd = sqlreader["pwd"].ToString();
  aca.num = int.Parse(sqlreader["num"].ToString());
  aca.peoplemax = int.Parse(sqlreader["peoplemax"].ToString());
  }
  myconnection.Close();
  return aca;

  }
  想在后台调用这个函数，取得返回的对象的相应值，为什么显示的值为0
  后台函数：
protected void Page_Load(object sender, EventArgs e)
  {
  if (!IsPostBack)
  {
  userName = Request["username"].ToString().Trim();
  style1 = Request["style1"].ToString().Trim();
  AAcademe aca = new AAcademe();
  aca = AAcademe.Find_Zys(userName);
  nZys.Text = aca.num.ToString().Trim();
  nTrs.Text = aca.peoplemax.ToString().Trim();
   
  }
  else
  {
  }
}
高手帮帮忙啊，毕业设计纠结啊。。。。期待您的回答，谢谢！
