Unable to call this procedure from c# because I did not find any oracledBtype which is used for

x_notes OUT NOCOPY sr_notes_det_table 

Here code for sr_notes_det_table

in my procedure call I have only problem with this out parameter

OracleParameter x_notes = cmd.Parameters.Add("x_notes", null);
x_notes.Direction = ParameterDirection.Output;

How can I captured this output parameter value in c#. please help or guide me how can I implement this correctly into the C#.
