File Upload Path in ASP.NET hosted Application

I have a web application in which i am saving files into the directory placed onto the root folder of my application , it works fine locally but when i hosting the application into the hosting environment it is not saving my file , locally i have save a filePath into the web.config like that 

 

and i was accessing it using that statement

Dim FilePath As String = ConfigurationManager.AppSettings("FilePath").ToString

 

How to achieve that on hosting server i have already tried

HttpContext.Current.Server.MapPath("~/Uploads/")

as well as

Server.MapPath("~/Uploads/") but it shows the local path address of my directory hierarchy .

 

 

 

Thanks in advance
