simple.data如何执行oracle包

Question

simple.data如何执行oracle包？？OracleParameter p1=新的OracleParameter（"mycs"，OracleType.Cursor）；创建或替换包pkg_members作为类型myrtype是参考CURSOR；

    PROCEDURE get (p_id NUMBER, p_rc OUT myrctype);
END pkg_members;

CREATE OR REPLACE PACKAGE BODY pkg_members
AS
    PROCEDURE get (p_id NUMBER, p_rc OUT myrctype)
    IS
       sqlstr   VARCHAR2 (500);
    BEGIN
       IF p_id = 0 THEN
          OPEN p_rc FOR
             SELECT *
               FROM members;
       ELSE
          sqlstr :=
             'select *
            from members where id=:p_id';
          OPEN p_rc FOR sqlstr USING p_id;
       END IF;
    END get;
END pkg_members; 

**当我这样做时：DbContext.Open（）.pkg_members_get（12）；以下错误：Simple.Data.Ado.AdoAdapterException：ORA-06550:第1行，第7列：PLS-00306:对"get"的调用中的参数数量或类型错误ORA-06550:第1行，第7列：PL/SQL：忽略语句**
