一个比较好看的网页翻页效果_.Net教程

推荐：使用存储过程实现用户登录(含代码)
程序代码： public SqlDataReader GetUserLoginByProc(string sUserName,string sPassword) { ///创建链接 SqlConnection myConnection = new SqlConnection( ConfigurationManager.ConnectionStrings[数据库连接字符].ConnectionString); ///创建Command S

显示效果：1 2 3 4 5>> ，点击了４后又显示 ，4 5 6 7 8>>并转到第４页 ，如果总共有１0页，  显示到6 7 8 9 10>>就不再显示了。
