I have the code
string xsltPath = System.Web.HttpContext.Current.Server.MapPath(@"App_Data") + "\" + TransformFileName
It returns
C:inetpubwwwrootwebsiteNameSERVICENAMEApp_DataFileName.xsl
Why am I getting the path to the ServiceController, SERVICENAME? I want the path to App_Data which is in
C:inetpubwwwrootwebsiteNameApp_DataFileName.xsl

Thank you for visiting the Q&A section on Magenaut. Please note that all the answers may not help you solve the issue immediately. So please treat them as advisements. If you found the post helpful (or not), leave a comment & I’ll get back to you as soon as possible.
Method 1
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);
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.
EDIT:
Can you define “absolute” and “relative” paths and how they compare to “physical” and “virtual” paths?
MSDN has a good explanation on relative, physical, and virtual paths. Take a look there.
Method 2
The answers given so far are what you are looking for, but I think, in your particular case, what you actual need is this:
AppDomain.CurrentDomain.GetData("DataDirectory").ToString()
This will still return the file path to the App_Data directory if that directory name changes in future versions of MVC or ASP.NET.
Method 3
Try doing like this (@"~/App_Data"). ~/ represents the root directory.
