Let me say first that I'm new to mono, and relatively new to C# (moving from C++), so the following problems could be a result of my inexperience, but I can't seem to get the sample code from go-mono.org to work, nor does my attempt in my own code to open the database connection work. (However, using sqlsharp, /Provider Oracle, and a valid connection string *does* work on the system, and I do have oracle installed and working correctly on the system in question.)


I've corrected the missing casting to strings in the demo code, but when it does compile successfully, and the connection string is valid I get:

Unhandled Exception: System.NullReferenceException: A null value was found where an object instance was required
in <0x00018> 00 System.Data.OracleClient.Oci.OciServerHandle:Attach ()
in <0x00470> 00 System.Data.OracleClient.Oci.OciGlue:CreateConnection (System.Data.OracleClient.OracleConnectionInfo)
in <0x0008e> 00 System.Data.OracleClient.OracleConnection:Open ()
in <0x00095> 00 .Test:Main (string[])


My own connection code, in an ASP.NET page used by mod_mono/apache2 returns:

System.MissingMethodException: A missing method exception has occurred.
in <0x00046> 06 System.Data.OracleClient.Oci.OciEnvironmentHandle:OCIEnvCreate (intptr&,System.Data.OracleClient.Oci.OciEnvironmentMode,intptr,intptr,intptr,intptr,int,intptr)

in <0x0008e> 00 System.Data.OracleClient.OracleConnection:Open ()
in <0x00080> 00 GSNB.GSNBDataAccess:.ctor ()


The version of mono is 0.23 (debs).

Any help will be appreciated!

Thanks,

David
