Connecting to Informix database from .Net

Question

What's the best way to connect to a Informix database from .Net?

I'm developing a client-server application based on a legacy Informix DB which used to be connected by JDBC.

I need it, from the most important to the least:

1. To be fast
2. DB server changes not needed
3. No ODBC and no dependencies, other than de .Net Framework 2.0

Thanks in advance for your help.

Answer 1

The connections strings to use with OleDb or ADO.NET can be found here.

Take a look at this article on how to connect to an Informix database using ADO.NET.

Answer 2

We connect to Informix from .NET, but we do it via web services that are written in FourJ's BDL

See if that helps. Also, what about the built in ODBC or OLEDB drivers? Have you tried those? Those might work.

You might like to investigate OpenLink's Multi-Tier Informix driver for ADO.Net (just install everything on the client): http://uda.openlinksw.com/dotnet/mt/dotnet-informix-mt/
