偶的错误是提示我from子句语法错误....但我感觉那个select语句不可能错的啊...

下面的是我仿照连接sql2000数据库而改写的...

using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Data.SqlClient;
using System.Data.OleDb;

namespace lianjiemdb
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            OleDbConnection mycn = new OleDbConnection();
            mycn.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + AppDomain.CurrentDomain.BaseDirectory + "plzc.mdb";
            OleDbCommand oledbCommand = new OleDbCommand();
            oledbCommand.Connection = mycn;
            oledbCommand.CommandType = CommandType.Text;
            oledbCommand.CommandText = "SELECT * FROM user";
            mycn.Open();
            OleDbDataReader dreader = oledbCommand.ExecuteReader(CommandBehavior.CloseConnection);
            string s = "";
            while (dreader.Read())
            {
                s += dreader["u_id"].ToString() + "\t"
                  + dreader["u_name"].ToString() + "\t"
                  + dreader["u_password"].ToString() + "\t"
                  + dreader["u_password2"].ToString() + "\r\n";
            }
            textBox1.Text = s;
            dreader.Close();
        }
    }
}


不知道怎么就错了....希望大大们能帮偶看看，给点提示...谢谢了.
