c# - 如何使应用程序中的路径相对，我在哪里做？ (MVC4)

转载作者：太空宇宙更新时间：2023-11-03 21:46:00

我有一个网络应用程序 (MVC4)。我想发布它。当我发布它时，我发现 Controller 的路径是从我的电脑查找我的目录，而不是从我的网站查找路径。

像这样:O:\Developing\MyWebApplication\Controllers\HomeController.cs 第 26 行中的 MyWebApplication\Controllers\HomeController.MyAction()

没有 Controller 链接的页面看起来很好。

如何在应用程序中创建相对路径，我在哪里做？

没有进一步的安全规则。托管商有一个 TrustLevel Medium，托管商唯一改变的是:

WebPermission : Unrestricted=”true”

OleDbPermission: Unrestricted=”true”

OdbcPermission : Unrestricted=”true”反射权限:标志=”RestrictedMemberAccess”

和

FileIOPermission : Read=”$AppDir$” PathDiscovery=”$AppDir$” Write=”$AppDir$” Append=”$AppDir$”

这是堆栈跟踪的来源:

最佳答案

你可以写

var path="~/AnyFolderInYourSolutionExplorer/,,,,,,";
~ is replaced with path to your project.

例如，如果在我的 MVC 应用程序中，一个名为“Images”的文件夹包含我的照片，那么访问该文件夹的方式如下

var img="~/Images/myPhoto.jpg";
