I am developing in vb.net. When I end my program, I get an error
Cannot access a disposed object.
Object name: 'System.Net.Sockets.NetworkStream'
Am I doing something wrong?

Here is more details:
Npgsql.dll!Npgsql.Npgsql.Connector.Finalize() Line 190 + 0x9 bytes

System.ObjectDisposedException occurred
Message=Cannot access a disposed object.
Object name: 'System.Net.Sockets.NetworkStream'.
at System.Net.Sockets.NetworkStream.Write(Byte[] buffer, Int32 offset, Int32 size)
at System.IO.BufferedStream.Flush()
at Npgsql.NpgsqlReadyState.Close(NpgsqlConnector context)


Nice catch!

I'll have a look at this.

Thanks for reporting.

Which version of Npgsql are you using, @GaryK4 ?

Are you getting this error when debugging your application inside vs.net?

I was using – net4. This was my original starting point.

I just tried (net4) and it does not have the issue!

I read somewhere that the 2.0. series were safer to use.

That is the highest 2.0 series that I could find.


Has 2.1.2 (net4) with the duplicate entries.

Because, I am in the MySql to PostgresQL migration testing phase, should I be using it?

Sorry if I am asking a lot of questions as a PostgreSQL / Npgsql newbie

Thanks for the help.

Ahhh, excellent!

I'm glad to know the latest version doesn't have this problem. is our previous stable version.

If you want some more new features, you should go with 2.1.x It is also stable and should be considered for new developments.

We are now working in the 2.2.x version with even more features (as well as new bugs :) ) that we are working on.

Yesterday we launched the 2.1.3 version. I still have to update the pgfoundry download page.

Please, let us know if you have any other problem when using Npgsql.
