Returing array from PL/SQL procedure

Question

Hi,
I am trying to return array from PL/SQL procedure. Heres is the code. I am getting an error "OracleParameter.ArrayBindSize is invalid ".
Will anybody let me know what is wrong in following code. or does anybody have code to return PL/SQL array using VB.NET.
oCommand.CommandText = "MyPack.TestVarchar2"
oCommand.CommandType = CommandType.StoredProcedure
Dim id As Integer = 10
Dim deptname As String()
Dim oParam1 As Oracle.DataAccess.Client.OracleParameter = New Oracle.DataAccess.Client.OracleParameter("id", Oracle.DataAccess.Client.OracleDbType.Int32)
Dim oParam2 As Oracle.DataAccess.Client.OracleParameter = New Oracle.DataAccess.Client.OracleParameter("deptname", Oracle.DataAccess.Client.OracleDbType.Varchar2)
oParam1.Direction = ParameterDirection.Input
oParam2.Direction = ParameterDirection.Output
oParam1.CollectionType = Oracle.DataAccess.Client.OracleCollectionType.None
oParam2.CollectionType = Oracle.DataAccess.Client.OracleCollectionType.PLSQLAssociativeArray
oParam1.Value = id
oParam2.Value = ""
oParam1.Size = 10
oParam2.Size = 20
oCommand.Parameters.Add(oParam1)
oCommand.Parameters.Add(oParam2)
oCommand.ExecuteNonQuery()
Thanks

Thanks Arnold for the reply..
Yes, I am trying to get result set in array which is unknow to me (No of rows return by the query). For the test I will pre-define the result set so that I will able to set ArrayBindSize.
I have read C# example but when I try to write it in VB.NET it gives me syntax error when I try to set the ArrayBindSize.
oParam.ArrayBindSize = new int[3]{15,23,13} // individual max size of 3 outputsWill you please let me know how to set ArrayBindSize (VB.NET) because I am new to this..
There is an example at otn "How to: Bind an Array to an ODP.NET Database Command" which does multiple INSERTs in one trip to database. This works fine. I need to do same for the SELECT statement which will return me multiple rows. I do not mean refCursor. If I use refCursor, it will make soft parse which I am trying to avoid using this Array techniq.
Thanks
