I am creating a website but when i put file info.xml in App_Data folder, and run website I got an error message "Could not find a part of the path 'c:\windows\system32\inetsrv\App_Data\info.xml' ". This is my code-behind in C#:

XmlDocument doc = new XmlDocument();
doc.Load("App_Data/info.xml");

Is there something wrong?, so anybody help me, please?. Thank first. 

Try this:

XmlDocument doc = new XmlDocument();
doc.Load(HttpContext.Current.Server.MapPath("~/App_Data/info.xml"));

Or simply:

XmlDocument doc = new XmlDocument();
doc.Load(Server.MapPath("~/App_Data/info.xml");

You'll need to use the first version if the method is static.
