If we use Server.MapPath("..") in ASP.NET 2.0 Then It Gives a error System.InvalidOperationException: "Failed to map the path '/'"
In ASP.Net 1.x, Server.MapPath("..") works fine in the older versions. The newer version does not support ".." and it is recommended to use "~" instead. For e.g.:
Server.MapPath("~/Path");
