Do you need to call Flush() on a stream or writer if you are using the “using” statement?

Question

I am not sure whether I need to call Flush() on the used objects if I write something like this:

using (FileStream...)
using (CryptoStream...)
u         


        

Answer 1

As soon as you leave the using block’s scope, the stream is closed and disposed. The Close() calls the Flush(), so you should not need to call it manually.
