How can you know if a stream is closed? [closed]

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). The exception happens when i call zip.Save(new MemoryStream()). I will ask my questions on their forum. Sorry, and thanks for the help.

You can check stream availability using: CanRead, CanSeek, CanWrite properties.

if you put the stream creation inside using it will do the closing and resource release for you EX:

using(Stream s = new MemoryStream())
{
 // do your operations
}
