Question

我有一个webapplication（MVC4）。我想发布它。当我发布它时，我发现控制器的路径是从我的电脑查找我的目录，而不是我网站上的路径。

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

没有指向控制器链接的页面看起来很好。

如何在应用程序中创建相对路径？我该怎么做？

没有其他安全规则。主机具有TrustLevel Medium，只有主机更改的内容是：

WebPermission：Unrestricted =“true”

OleDbPermission：Unrestricted =“true”

OdbcPermission：Unrestricted =“true” ReflectionPermission：Flags =“RestrictedMemberAccess”

和

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

这是堆栈跟踪的来源：

Answer 1

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，名为“Images”的文件夹会对我的照片进行控制，那么访问该文件就是

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

Answer 2

你应该只能指定动作和控制器（没有控制器后缀） MVC非常聪明，可以寻找控制器。所以这应该有效：

@Html.ActionLink("description","MyAction","Home")

Answer 3

在MVC 4中，您需要做的就是：

 <img src="~/SomeFolder/someImage.jpg" />

〜符号确保MVC将在您的网站的根目录中查找该文件。在MVC 4之前，你必须这样做：

 <img src="@Url.Content("~/SomeFolder/someImage.jpg")" />
