OracleNumber Conversion Issue

[Guest]

Running the below code:
convert.toint32(oracle_Command.ExecuteOracleScalar)

Results in the below error:
Run-time exception thrown : System.InvalidCastException - Specified cast is
not valid.

The sql being ran results in:
10438

Any help would be appreciated

Thanks
