Connecting to Oracle 10g from .NET
- by Xinus
I am trying to connect to oracle server located at some IP address but always get error as
System.TypeInitializationException:
The type initializer for
'Oracle.DataAccess.Client.OracleConnection'
threw an exception. ---
Oracle.DataAccess.Client.OracleException
The provider is not compatible with
the version of Oracle client at
Oracle.DataAccess.Client.OracleInit.Initialize()

Here is a test file

{
try {
string oradb = "Data Source=(DESCRIPTION=(ADDRESS_LIST="

+ "(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=ORCL)));"
+ "User Id=<user id>;Password=<some password>;";
OracleConnection conn = new OracleConnection(oradb); // C#
conn.Open();
}
catch (Exception ex){
Label1.Text = ex.ToString();
}
}
}
}
I have installed 10gR2 client and oracle 10gR2 provider for ASP.NET. Am I missing anything ?
