如何在c#中传递数组Oracle参数

我在使用c#传递数组参数时遇到问题，我的代码是：

private OracleDataAdapter da;
private OracleConnection cnn;
public DataTable select_ids_between_friends(int cod, List<int> excludeList) {
    DataTable dt = new DataTable();
    try
    {
        using (cnn = new OracleConnection(Properties.Settings.Default.connectionString1))
        {
            cnn.Open();
            da = new OracleDataAdapter("PROC_SELECT_IDS_BT_FRIENDS", cnn);
            da.SelectCommand.CommandType = CommandType.StoredProcedure;
            da.SelectCommand.Parameters.Add("CURSOR", OracleDbType.RefCursor, ParameterDirection.Output);
            da.SelectCommand.Parameters.Add("COD_US", OracleDbType.Int32, cod, ParameterDirection.Input);
            da.SelectCommand.Parameters.Add(new OracleParameter("IDS_FRIEND", OracleDbType.Int32));
            da.SelectCommand.Parameters[2].CollectionType = OracleCollectionType.PLSQLAssociativeArray;
            da.SelectCommand.Parameters[2].Value = excludeList.ToArray();
            da.SelectCommand.Parameters[2].Size = excludeList.Count;
            da.Fill(dt);
            cnn.Close();
        }
    }
    catch (Exception ex)
    {
    }
    return dt;
}

在数据库中，我创建了数组和存储过程，如下所示：这是Oracle类型：

CREATE TYPE FACEBOOK.ARRAY_ID_FRIENDS AS TABLE OF INT;

最后，这是我的程序：

CREATE OR REPLACE PROCEDURE PROC_SELECT_IDS_BT_FRIENDS
(DATA_CURSOR OUT SYS_REFCURSOR,COD_US IN INT, IDS_FRIEND IN FACEBOOK.ARRAY_ID_FRIENDS) IS
BEGIN
    OPEN DATA_CURSOR FOR 
    SELECT ID_USER1,ID_USER2 FROM T_FRIENDSHIP WHERE ID_USER2 NOT IN(SELECT COLUMN_VALUE FROM TABLE(IDS_FRIEND)))
END;
/

显示的错误为PLS-00306:调用PROC_SELECT_IDS_BT_FRIENDS中的参数数量或类型错误。请帮帮我。提前谢谢。

da.SelectCommand.Parameters.Add(new OracleParameter("IDS_FRIEND", OracleDbType.Int32));
