Select();

            Select("id>='3' and name='3--hello'");//支持and

            Select("id>='3' or id='1'");//支持or

            Select("name like '%hello%'");//支持like   

            Select("id>5","id desc");

            Select("id>5", "id desc",DataViewRowState.Added);

DataTable dt = new DataTable();
            dt.Columns.Add("timed", typeof(DateTime));

            DataRow dr = null;
            dr = dt.NewRow();
            dr["timed"] = DateTime.Parse("2013-9-26 12:00:00");
            dt.Rows.Add(dr);

            dr = dt.NewRow();
            dr["timed"] = DateTime.Parse("2013-9-27 12:00:00");
            dt.Rows.Add(dr);

            DateTime dd1 = DateTime.Parse("2013-9-26 22:00:00");
            DateTime dd2 = DateTime.Parse("2013-9-27 12:00:00");

            DataRow[] drs = dt.Select("timed > '" + dd1 + "' and timed <= '" + dd2 + "'");//筛选出 2013-9-27 12:00:00
