I have an XML file named PageData.xml in my App_Data folder. I want to populate an XDocument with this file using XDocument.Load.
If I supply the full physical path it works, ie:
XDocument vXDoc = XDocument.Load("/Work/Project/Web/100413 Dev/App_Data/PageData.xml");
...where "Work" is a folder on my C: drive.
If I try a relative path like this, though, I get a DirectoryNotFoundException:
XDocument vXDoc = XDocument.Load("AppData/PageData.xml");
"Could not find a part of the path 'C:\\Program Files (x86)\\Common Files\\Microsoft Shared\\DevServer\\10.0\\AppData\\PageData.xml'."
This is obviously wrong, but there must be an easy way to set the correct relative path? What am I overlooking? Your help is appreciated.
There's a couple of ways you can do it. You can use Server.MapPath() to turn a virtual directory into a physical directory path:
XDocument xdoc = XDocument.Load(Server.MapPath("/App_Data/PageData.xml"));
Or you can use Request.PhysicalApplicationPath as well, like so:
var path = Path.Combine(Request.PhysicalApplicationPath, "App_Data\\PageData.xml");
XDocument xdoc = XDocument.Load(path);
In either case, the problem is that the current working directory of the worker process is usually not set to the application directory (this is because working directory is a process-wide property, and a single process can host multiple web sites). More information is here .
