.Net calling Oracle Array bound stored procedure output VarChar2 - sql

Question

I'm calling an Oracle array bound stored procedure from C#
I can add output parameters of type NUMBER, and the return values are correctly populated.
If I try to use output values of type VARCHAR2, I'm getting "OracleParameter.ArrayBindSize is invalid" Exception.
This works:
CREATE OR REPLACE PROCEDURE CLOUDDBA.INSERTTEST (
P_VALUE NUMBER,
P_CODE OUT NUMBER--,
-- P_MESSAGE OUT VARCHAR
)
AS
BEGIN
P_CODE := P_Value ;
--P_MESSAGE := '';
IF P_Value = 1 THEN
P_CODE := 1;
--P_MESSAGE := 'ONE';
END IF;
END INSERTTEST;
C# code:
var values = new int[] { 1, 2, 3 };
ocmd.CommandText = "INSERTTEST";
ocmd.CommandType = CommandType;
ocmd.BindByName = true;
ocmd.ArrayBindCount = 3;
ocmd.Transaction = transaction;
ocmd.Parameters.Clear();
var pValue = new OracleParameter("P_VALUE", OracleDbType.Int32, 255, ParameterDirection.Output) { Value = values };
ocmd.Parameters.Add(pValue);
var pVCode= new OracleParameter("P_CODE", OracleDbType.Int32, 255, ParameterDirection.Output);
ocmd.Parameters.Add(pVCode);
This blows up:
CREATE OR REPLACE PROCEDURE CLOUDDBA.INSERTTEST (
P_VALUE NUMBER,
P_CODE OUT NUMBER,
P_MESSAGE OUT VARCHAR
)
AS
BEGIN
P_CODE := P_Value ;
P_MESSAGE := '';
IF P_Value = 1 THEN
P_CODE := 1;
P_MESSAGE := 'ONE';
END IF;
END INSERTTEST;
C# code:
var values = new int[] { 1, 2, 3 };
ocmd.CommandText = "INSERTTEST";
ocmd.CommandType = CommandType;
ocmd.BindByName = true;
ocmd.ArrayBindCount = 3;
ocmd.Transaction = transaction;
ocmd.Parameters.Clear();
var pValue = new OracleParameter("P_VALUE", OracleDbType.Int32, 255, ParameterDirection.Output) { Value = values };
ocmd.Parameters.Add(pValue);
var pVCode= new OracleParameter("P_CODE", OracleDbType.Int32, 255, ParameterDirection.Output);
ocmd.Parameters.Add(pVCode);
var pVMessage= new OracleParameter("P_MESSAGE", OracleDbType.Varchar2, 255, ParameterDirection.Output);
ocmd.Parameters.Add(pVMessage);

Found the solution.
Use SQL Server.
Need to specify ArrayBindSize.
replace
var pVMessage = new OracleParameter("P_MESSAGE", OracleDbType.Varchar2, 255, ParameterDirection.Output);
with
var pVMessage = new OracleParameter("P_MESSAGE", OracleDbType.Varchar2, 255, ParameterDirection.Output) {ArrayBindSize = new int[]{255, 255, 255}};
