Answer 1

You can do:

String absolutePath = Server.MapPath(myRelativePath);

Answer 2

try like HostingEnvironment

string logDirectory = HostingEnvironment.MapPath("~") + "\\" + "App_Data\\MakeMyBill.sdf";

or

string logDirectory =Server.MapPath("~/App_Data/MakeMyBill.sdf")

or on any folder

     string filePath = @"D:\file\";
        string directoryName = Path.GetDirectoryName(filePath);
        filePath = directoryName + @"\file.xml";
