在使用MVC3使用Server.Mappath [英] Using Server.MapPath in MVC3

问题描述

我有code

string xsltPath = System.Web.HttpContext.Current.Server.MapPath(@"App_Data") + "\\" + TransformFileName

它返回

C：\\的Inetpub \\ wwwroot的\\ websiteName \\ SERVICENAME \\ App_Data文件\\ FileName.xsl

为什么我收到了路径的ServiceController， SERVICENAME ？我想路径的App_Data这是

Why am I getting the path to the ServiceController, SERVICENAME? I want the path to App_Data which is in

C：\\的Inetpub \\ wwwroot的\\ websiteName \\ App_Data文件\\ FileName.xsl

推荐答案

您需要指定您希望从虚拟根目录开始：

You need to specify that you want to start from the virtual root:

string xsltPath = Path.Combine(System.Web.HttpContext.Current.Server.MapPath(@"~/App_Data"), TransformFileName);

此外，最好的做法是使用 Path.Combine 为路径结合起来，而不是连接字符串。 Path.Combine 将确保你不会用双路径分隔符的情况下结束了。

Additionally, it's better practice to use Path.Combine to combine paths rather than concatenate strings. Path.Combine will make sure you won't end up in a situation with double-path separators.

修改

你能定义绝对和相对路径和如何比较物理和虚拟的路径？

Can you define "absolute" and "relative" paths and how they compare to "physical" and "virtual" paths?

MSDN有很好的解释。看看那里。

MSDN has a good explanation on relative, physical, and virtual paths. Take a look there.
