C#调用ORACLE存储过程返回结果集

Oracle中scott用户下创建存储过程：
(注：从9i开始有了sys_refcursor这种类型，在以前的Oracle版本中需要使用REF CURSOR,并且还需放在一个程序包中)
create or replace procedure sp_getdept
(result out sys_refcursor)
as
begin
open result for select * from dept;
end;

===================================================
.net环境下（用的WINDOWS程序，WEB基本相同；环境为VS2005）
==记着先添加引用System.Data.OracleClient
using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Text;using System.Windows.Forms;using System.Data.OracleClient; namespace WindowsApplication1{ public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void Form1_Load(object sender, EventArgs e) { OracleConnection con = new OracleConnection("server=orcl;uid=scott;pwd=tiger"); OracleCommand cmd = new OracleCommand("sp_getdept",con); cmd.CommandType = CommandType.StoredProcedure; OracleParameter p1 = new OracleParameter("result", OracleType.Cursor); p1.Direction = System.Data.ParameterDirection.Output; cmd.Parameters.Add(p1); OracleDataAdapter da = new OracleDataAdapter(cmd); DataSet ds = new DataSet(); da.Fill(ds); this.dataGridView1.DataSource = ds.Tables[0]; } }}
