[Mono-list] Problem closing Streams

[Carlos Guzmán Álvarez]

Hello:


I´m making test of the Firebird ADO.NET provider on linux Red Hat 8.0 
with the latest sources of mono, i have a problem, I have BinaryReader 
used for reading data sent by the server, and a BinaryWriter for send 
data to the server created as:

	db.Output = new XdrOutputStream(new 
BufferedStream((System.IO.Stream)db.DbNetworkStream));
	
	db.Input  = new XdrInputStream(new 
BufferedStream((System.IO.Stream)db.DbNetworkStream));


When i disconnect from a database i make:

	db.Input.Close();
	db.Output.Close();  // Here gives an exception
	db.DbNetworkStream.Close();
	...


This works well on Ms .Net, and it has been working well on old versions 
of mono (0.17).



The exception is:
