I have a method with a Stream for input :

```
public void Export(Stream finalOutPutStream)

```

For test purposes, i call it with a memory stream, like this :

```
// When
_exporter.Export(new System.IO.MemoryStream());

```

But when, in the method, i want to write on this memory stream, i get a ObjectDisposedException.

This stream is not enclosed in a using statement, i do not call explicitely .Dispose().

What happened ?

Thanks :)

EDIT : my bad, the problem is from the third party writer ([DotNetZip](http://dotnetzip.codeplex.com/)). The exception happens when i call zip.Save(new MemoryStream()). I will ask my questions on their forum.
Sorry, and thanks for the help.
