如何在WebAPI Controller中从物理路径生成绝对路径

Question

In a WebAPI Controller, how to return the absolute or relative path to a file giving that I only know the full physical file path?

I found a lot of information for the opposite using System.Web.Hosting.HostingEnvironment.MapPath, but I need the opposite (from physical to absolute/relative).

Is this the best way of doing it?:

Url.Content("~/" + myFullPath.Replace(System.Web.Hosting.HostingEnvironment.ApplicationPhysicalPath,""))

Answer 1

您可以从文件的物理路径中删除ApplicationPhysicalPath属性的值。
