我们可以将ImageUrl设置为物理路径吗？
我有一个图像控件，我必须将其ImageUrl设置为物理路径，例如C:\image\image1.jpg< /code> 但控制仅采用虚拟路径。如果我们拥有的路径是物理路径，如何显示该图像？
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?

您可以在 IIS 中创建虚拟文件夹。然后，您可以将图像控件的路径设置为虚拟文件夹的路径。
You could create a Virtual Folder in IIS. You can then set your image control's path to be that of the Virtual Folder.
否，因为客户端（浏览器）无法访问该文件。它需要是一个暴露于“互联网”的文件。您需要将图像移动到其他位置，并使用波形符
~引用它，这意味着“应用程序路径”：~/Images/images1.jpg。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.你不能，图像必须位于 Web 根目录中，最终用户才能看到它，因此它将有一个虚拟路径。
You cannot, the image has to be in the web root for the end user to see it and it therefore will have a virtual path.
您需要一个
代理对象。当页面需要时，该对象应该从物理路径加载图像作为服务器。它可以像将其加载到静态变量一样简单，也可以是复杂的惰性（按需加载图像）代理，并带有用于跟踪图像更改的文件系统观察器。它可以是一个控件或 Web 服务（也许需要身份验证）。
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).
图像仍然必须放置在本地服务器根文件夹中。不是物理路径。
Still the image has to be placed in local server root folder. Not a physical path.
不。作为软件开发人员，我们不直接与物理层交互。物理层（通常）是旋转盘上的磁性颗粒。没有物理路径可以到达它。我们在物理层之上的几个抽象层上进行操作。
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.
