我想做一个添加滚动图片,但是我不知道到底有几张我该怎么办
我想做一个添加滚动图片,但是我不知道到底有几张我该怎么办我想知道两种办法一中是URL的一种是从数据库里读的(我知道怎么从数据库里读图片) --------------------编程问答-------------------- 何必知道有几张？datagrid之类的控件，谁去管它有多少记录了- -! --------------------编程问答-------------------- 向上滚动

操作目录的命名空间及类
//操作目录的几个类
System.IO.Directory; //里面全是静态方法，可能直接调
System.IO.DirectoryInfo dirinfo = new System.IO.DirectoryInfo(); //也有很多方法
//操作文件的几个类
System.IO.File; //里面全是静态方法，可能直接调
System.IO.FileInfo fileinfo = new System.IO.FileInfo(); //也有很多方法
//只能告诉你这些类了，里面的方法你自已去查吧，很有用．可以遍历一个目录的所有文件，及文件的所有信 息，包括地址
//熟悉里面的方法，自已去灵活应该吧
--------------------编程问答-------------------- 从数据库中读出来就可以了啊 --------------------编程问答-------------------- 用aspnet自带的控件 --------------------编程问答-------------------- 存的时候只存图片图径,读出来拼上去就行了 --------------------编程问答-------------------- 感谢大家，我也需要这样的东西
补充：.NET技术 , ASP.NET
