    .STUserUpdatePwdaspxcs的主要代碼及其解釋

    STUserUpdatePwdaspxcs主要實現了修改密碼的功能
    private void Page_Load(object sender SystemEventArgs e)
    {
             // 在此處放置用戶代碼以初始化頁面
             if(Session[STNickName] != null)
             {
                       //獲得數據庫連接字符串
                       string STconnection = ConfigurationSettingsAppSettings[strconnection];
                       STconn = new SqlConnection(STconnection);
                       //獲取登錄用戶的登錄名
                       STNickName = Session[STNickName]ToString();
                       STconnOpen();
                      //創建查詢登錄用戶密碼的sql語句
                       string STstrsql = select STUserPwd from STUser where STNickName = + STNickName + ;
                       //創建數據庫的SqlCommand對象
                       SqlCommand STcmd = new SqlCommand(STstrsqlSTconn);
                       //執行SqlCommand對象中數據的讀取
                       SqlDataReader STsdr = STcmdExecuteReader();
                       while(STsdrRead())
                       {
                                //將獲得的用戶名密碼保存到會話中
                                Session[STUserPwd] = STsdr[STUserPwd];
