C#2005 如何打开microsoft office excel 2007

引用的COM组件是 Microsoft Excel 12.0 Object Library
              Microsoft Office 12.0 Object Library

将指定的2007 Excel文件打开，填充到DataSet中；

     DataSet ds = new DataSet();
     string strCon = " Provider = Microsoft.Jet.OLEDB.4.0 ;Persist Security Info=False; Data Source = " + fileName + ";Extended      Properties=Excel 8.0";
                OleDbConnection oConn = new OleDbConnection(strCon);
                string strCom = " SELECT * FROM [Sheet1$]";
                OleDbDataAdapter myCommand = new OleDbDataAdapter(strCom, oConn);
                myCommand.Fill(ds);
                oConn.Close();

//会抛出异常“外部表不是预期的格式”
用打开数据库的方式打开2007 Excel文件需要怎么改写？
