一個比較好看的網頁翻頁效果_.Net教程

推薦：使用存儲過程實現用戶登錄(含代碼)
程序代碼： public SqlDataReader GetUserLoginByProc(string sUserName,string sPassword) { ///創建鏈接 SqlConnection myConnection = new SqlConnection( ConfigurationManager.ConnectionStrings[數據庫連接字符].ConnectionString); ///創建Command S

顯示效果：1 2 3 4 5>> ，點擊了４后又顯示 ，4 5 6 7 8>>并轉到第４頁 ，如果總共有１0頁，  顯示到6 7 8 9 10>>就不再顯示了。
