我们可以将ImageUrl设置为物理路径吗？

Question

I have a image control and I have to set it's ImageUrl to a physical path like C:\\image\\image1.jpg but control takes virtual path only. How to show that image if path we have is physical path?

Answer 1

You could create a Virtual Folder in IIS . You can then set your image control's path to be that of the Virtual Folder.

Answer 2

No because the client (browser) can't access that file. It needs to be a file that is exposed to "the internet". You will need to move the image elsewhere and reference it with the tilde ~ which means "application path": ~/Images/images1.jpg .

Answer 3

您不能，该图像必须位于网络根目录中才能让最终用户看到它，因此它将具有虚拟路径。

Answer 4

You need a Proxy Object . This object should load the image from physical path as an server it when the page needs it. It can be as simple as loading it to a static variable or a complex Lazy (load image on demand) proxy with file system watcher for tracking changes of images.

It could be a control or web-service (maybe authentication is needed).

Answer 5

Still the image has to be placed in local server root folder. Not a physical path.

Answer 6

No. We, as software developers, do not directly interact with the physical layer. The physical layer is (usually) magnetic particles on a spinning platter. There is no physical path to it. We operate at several layers of abstraction above the physical layer.
