1、資料來源

       從sql server中匯出,在匯出選擇目標伺服器時,要選擇microsoft jet database engine,否則資料會無法讀出

2、資料庫連接

                   OleDbConnection,OleDbCommand,OleDbDataAdapter,

       如果是在控制台中,可以利用OleDbDataReader。

3、典型代碼

                   string apppath = System.Windows.Forms.Application.StartupPath //擷取整個檔案路徑名

                   apppath += @"\student1.mdb";

                   string strCon = "Provider = Microsoft.Jet.OLEDB.4.0;Data Source = " +apppath;

                   OleDbConnection oleConn = new OleDbConnection(strCon);

            try
            {
                oleConn.Open();
                string strQuery = "select * from student_scyx ";
                OleDbDataAdapter oleda = new OleDbDataAdapter(strQuery, oleConn);
                oleda.Fill(ds, "DataStudent");
                return ds;
            }
            catch (Exception ee)
            {
                Console.WriteLine(ee.Message.ToString());
                throw (ee);
            }
            finally
            {
                oleConn.Close();
            }
