ASP.NET MVC - Find Absolute Path to the App_Data folder from Controller

string path = AppDomain.CurrentDomain.GetData("DataDirectory").ToString();

This is probably a more "correct" way of getting it.

ASP.NET MVC1 -> MVC3

string path = HttpContext.Current.Server.MapPath("~/App_Data/somedata.xml");

---

ASP.NET MVC4

string path = Server.MapPath("~/App_Data/somedata.xml");

HttpServerUtility.MapPath Method
