Determining Status of FileStream, etc.

[TedN]

Is there a way to determine if a FileStream, CryptoStream, etc. is closed or open.

Ive tried things like:

If fs.Closed() = True Then
    Blah, blah
End If

But that doesnt work.

Thanks,
Ted

CanRead and CanWrite

I suggest checking both the CanRead and CanWrite properties. If the Stream is closed, they will both return false. If the Stream is open, I would expect at least one of them to return true, otherwise the Stream is essentially useless.

If Not (fs.CanRead Or fs.CanWrite) Then
    Assume closed
End If

Good luck
