Problem Querying "Col" View

Question

Hello guys,
I have some problem querying the "Col" View of Sys.
I have tested the following scenarios:
C# Code:
using (OracleConnection con = new OracleConnection("MyConnection"))
con.Open();
using (OracleDataReader reader = new OracleCommand("SELECT * from Col", con).ExecuteReader())
while (reader.Read())
Console.WriteLine(String.Format("Default Value: {0}",Convert.ToString(reader["DEFAULTVAL")));
If I tested this code using System.Data.OracleClient It works Fine and if there is sopme default Value it would be written.
If I change the driver using Oracle.DataAccess.dll from the last release.
Always, depite exists the DefaultValue it through "".
If I execute the query from TOAD I get the correct value also.
If I Change the code to use a OracleDataAdapter (:() I get an exception of Long Data Type.
My Oracle DB info is:
Oracle Database 10g Enterprise Edition Release 10.2.0.5.0 - 64bi
PL/SQL Release 10.2.0.5.0 - Production
CORE     10.2.0.5.0     Production
TNS for 64-bit Windows: Version 10.2.0.5.0 - Production
NLSRTL Version 10.2.0.5.0 - Production
VS version is VS2010
Any workAround?
Regards!

Finally, I get solved:
I need to add "InitialLONGFetchSize= -1" to the command configuration.
