ODP ArrayBindSize

Question

My Oracle Package Procedure signature is
PROCEDURE Get_Object_Details(
p_ObjectID IN VARCHAR2,
p_FullLoad IN VARCHAR2,
p_PropName OUT gt_PropNames,
p_PropValue OUT gt_PropValues,
gt_PropNames,gt_PropValues etc. are of type table and definition is as follows.
TYPE gt_PropNames IS TABLE OF VARCHAR2(50)INDEX BY BINARY_INTEGER;
I want to execute the Procdure from my .NET application using ODP.
Sample Code which i am using is :
string strConnString = "User Id=xyz;Password=xyz;Data
Source=(DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = Abc)(PORT = 1521)))(CONNECT_DATA = (SERVER = DEDICATED)(SERVICE_NAME = EX_SID)));";
OracleParameter param_ObjectID = new
OracleParameter("p_ObjectID",OracleDbType.Int32);
param_ObjectID.Direction = ParameterDirection.Input;
param_ObjectID.Value = Convert.ToInt32(6);
OracleParameter strFullLoad = new
OracleParameter("p_FullLoad",OracleDbType.Varchar2);
strFullLoad.Direction = ParameterDirection.Input;
strFullLoad.Value = "T";
OracleParameter p_PropName = new
OracleParameter("p_PropName",OracleDbType.Varchar2);
p_PropName.CollectionType = OracleCollectionType.PLSQLAssociativeArray;
p_PropName.Direction = ParameterDirection.Output;
p_PropName.Size = 1000;
OracleParameter p_PropValue = new OracleParameter("p_PropValue",
OracleDbType.Varchar2);
p_PropValue.CollectionType = OracleCollectionType.PLSQLAssociativeArray;
p_PropValue.Direction = ParameterDirection.Output;
p_PropValue.Size = 1000;
OracleParameter[] param =
{param_ObjectID,strFullLoad,p_PropName,p_PropValue};
try
OracleHelper.ExecuteNonQuery(strConnString,CommandType.StoredProcedure,"PKG1.Procedure1",param);
catch(Exception ee)
MessageBox.Show(ee.Message.ToString());
But is giving any Error. The Error is OracleParameter.ArrayBindSize is invalid.
I don't want to Set this property at design time. Because.. it is dynamic.
Please Post same sample code.

I am guessing you got this working already but here it is just in case somebody else could use it.
          // allows one to build a variable sized array
          private static OracleParameter BuildAssociativeArray(
               string paramName
               ,OracleDbType paramType
               ,object[] values
               ,int bindSize
               ,ParameterDirection paramDirection
               ,bool skipNullItems)
               int                    paramSize = 0;
               object[]     paramValues;
               // set the parameter size and load up the parameter values and bind size
               if (!skipNullItems)
                    paramSize = values.Length;
               else
                    for (int i = 0; i < values.Length; i++)
                         if (values[i] != null)
                              paramSize++;
                         else
                              break; // stop at first null
               paramValues = new object[paramSize];
               int[] bindArray = new int[paramSize];
               for (int i = 0; i < paramSize; i++)
                    paramValues[i] = values;
                    bindArray[i] = bindSize;
               // create the parm now
               OracleParameter parm = new OracleParameter(
paramName
                    , paramType
                    , paramValues.Length == 0 ? (object)DBNull.Value : paramValues
                    , paramDirection);
               parm.Size = paramSize;
               parm.CollectionType = OracleCollectionType.PLSQLAssociativeArray;
               if (paramSize != 0)
                    parm.ArrayBindSize = bindArray;
               else
               return parm;
and here is a sample of it being called
                    parmValues = new string[ArrayLen];
                    for (int i = 0; i < parmValues.Length; i++)
                         if (contact.ShippingAddress[i] == null)
                              parmValues[i] = null;
                         else
                              parmValues[i] = contact.ShippingAddress[i].ZIP5;
                    parms.Add(BuildAssociativeArray("p_ship_zip_5_code"
                         , OracleDbType.Char
                         , parmValues
                         , 5
                         , ParameterDirection.Input
                         , false));
