Hi


I want to retrive image in repeater in asp.net From Directory
There is a folder with a Name of documents and category that is fixed ,but under category folder there is a directory with a name of category Id and Under Category Id there is a directory with a name a of subcategory Id i want to retrieve Image from Subcategory Directory.

 string path = Path.Combine(Server.MapPath(@"~/Documents/Category/Cat_Id/Sub_Cat"+ ext));
   Directory.GetFiles(path);

</pre>

推荐答案

为什么使用Path.Combine，然后只传递它一个参数？

Why are you using Path.Combine, and then only passing it one parameter?

string path = Path.Combine(Server.MapPath(@"~/Documents/Category/Cat_Id/Sub_Cat"+ ext));

如果你通过两个问题，你的问题可能会消失...

You problem may go away if you pass two...

string path = Path.Combine(Server.MapPath(@"~/Documents/Category/Cat_Id/Sub_Cat"), ext);

如果图像在您的网站空间之外，您无法使用http直接为它们提供服务，因此您需要使用处理程序将它们推送到客户端。您可以重复使用此链接中的大部分代码

您只需将其从数据库路径更改为文件夹结构。

If the images are outside of your webspace you can't server them directly using http so you'll need to push them to the client using handlers. You can re-use most of the code from this link

you'd just need to change it from getting the path from a database to your folder structure.
