修改用戶信息（modify_user_info）
加載頁面：

// 在此處放置用戶代碼以初始化頁面
if( ! Page.IsPostBack)

cmd.Connection = conn;
//打開連接,執行操作,返回閱讀器
conn.Open();
SqlDataReader reader = cmd.ExecuteReader();
if(reader.Read())
{
this.lblusername.Text=Convert.ToString(reader["user_name"]);
this.ddlnian.SelectedValue=Convert.ToDateTime(reader["user_birthday"]).ToString("yyyy");

this.ddlquestion.SelectedValue=Convert.ToString(reader["user_question"]);
this.txtanswer.Text=Convert.ToString(reader["user_answer"]);
this.txtemail.Text=Convert.ToString(reader["user_email"]);
this.rblsex.SelectedValue=Convert.ToString(reader["user_sex"]);
}
//關閉數據庫,釋放連接
reader.Close();
conn.Close();
}// 在此處放置用戶代碼以初始化頁面
}
