Just remove that using statement - you are passing disposed object reference to File method and you that's the reason why you get exception. From MSDN,

The StreamWriter object calls Dispose on the provided Stream object when StreamWriter.Dispose is called.

I believe File will dispose stream by itself after usage (not verified by looking at source code).

UPDATE:

writer.Flush(); before return statement should help you
