create file on localhost (Web server physical path)

Question

Currently I am working on asp.net website and I am not very much familiar with asp.net. I have a WebForm and when user clicks on Submit button a .txt file should be get created on server(Text File name is ID entered by user which is unique.)
I used following to create the file.

File.Create( Server.MapPath("~") + id + @".txt");  

But this gives me error when the site is running on the localhost of my pc.
Access to the path 'C:\\inetpub\\wwwroot\\XXX\\YYY.txt' is denied.

This is something related with access permission. What should I do to fix this. Please advice me.
