ASP.net Create a directory - Access denied

I am making an ASP.NET MVC application and I would like users to be able to save files to a folder.

I have this code:

if (!Directory.Exists("~/CSVfiles/" + userDetails.Username))
  Directory.CreateDirectory("~/CSVfiles/" + userDetails.Username);

So if the user does not have a folder in the directory specified then make one. Firstly is this a correct way to find a folder -> "~/CSVfiles/"

When it has created this folder I then want to be able to save a file to that folder I have this code:

System.IO.File.WriteAllLines("~/CSVfiles/" + userDetails.Username + "/doc.csv", CSV);

I have List CSV <- this is a list of strings comma separated.

I am currently getting this error:

System.UnauthorizedAccessException
{"Access to the path '~/CSVfiles/User1' is denied."}

Directory is part of the common IO namespace and does not understand shorthand signs like '~' of ASP.NET. You have to convert it to some actual path... You may use Page.ResolveUrl or VirtualPathUtility...

Your asp.net users need to have permission on that folder. Check if asp.net app pool users have write access to your folder.
