Call procedure of Oracle apps by C# not working - asp.net-mvc

Question

Call procedure from C#:
DataSet ds = new DataSet();
using (OracleConnection con = new OracleConnection(WebConfigurationManager.ConnectionStrings["DataContext"].ConnectionString))
{
using (OracleCommand cmd = new OracleCommand("CS_SERVICEREQUEST_PUB.GET_SR_NOTES_DETAILS", con))
{
con.Open();
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Clear();
OracleParameter p_api_version = cmd.Parameters.Add("p_api_version", OracleDbType.Int32);
p_api_version.Direction = ParameterDirection.Input;
p_api_version.Value = 4;
OracleParameter p_incident_id = cmd.Parameters.Add("p_incident_id", OracleDbType.Int32);
p_incident_id.Direction = ParameterDirection.Input;
p_incident_id.Value = 860636;
OracleParameter p_incident_number = cmd.Parameters.Add("p_incident_number", OracleDbType.Varchar2, 50);
p_incident_number.Direction = ParameterDirection.Input;
p_incident_number.Value = "480777";
OracleParameter x_notes = cmd.Parameters.Add("x_notes", null); // having issue with this
x_notes.Direction = ParameterDirection.Output;
OracleParameter x_return_status = cmd.Parameters.Add("x_return_status", OracleDbType.Varchar2, 50);
x_return_status.Direction = ParameterDirection.Output;
OracleParameter x_msg_count = cmd.Parameters.Add("x_msg_count", OracleDbType.Varchar2, 50);
x_msg_count.Direction = ParameterDirection.Output;
OracleParameter x_msg_data = cmd.Parameters.Add("x_msg_data", OracleDbType.Varchar2, 50);
x_msg_data.Direction = ParameterDirection.Output;
using (OracleTransaction tran = con.BeginTransaction(IsolationLevel.ReadCommitted))
{
try
{
cmd.Transaction = tran;
cmd.ExecuteNonQuery();
using (OracleDataAdapter da = new OracleDataAdapter())
{
da.SelectCommand = cmd;
da.Fill(ds);
}
tran.Commit();
}
catch (OracleException ex)

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
TYPE SR_NOTES_DET_REC IS RECORD (
NOTES JTF_NOTES_VL.NOTES%TYPE ,
NOTES_DETAIL JTF_NOTES_VL.NOTES_DETAIL%TYPE ,
NOTE_TYPE JTF_NOTES_VL.NOTE_TYPE%TYPE ,
NOTE_TYPE_MEANING JTF_NOTES_VL.NOTE_TYPE_MEANING%TYPE ,

CREATED_BY_USER_TYPE VARCHAR2(30),
CONTACT_PARTY_ID NUMBER);
TYPE sr_notes_det_table IS TABLE OF SR_NOTES_DET_REC INDEX BY BINARY_INTEGER;
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#.
