TRY CATCH妙用

今天跟了一天的程序,直到4点多,还没搞定一个BUG,很是郁闷,看了一会新闻,最后一刻,终于搞定了.问题是:checkResult = checkCOShiptoValidate(e, coNo, shiptoNo, thisShipto, out alertResult);代码总是报错,先是跟进去看,但是太复杂了,并且,每次重现这个错误都要好长时间,最后,发现,出错后,点击IE上的BACK按钮,就没错了,于是想出了这个方法:如果出错,就把页面刷新一下,

       dg_shipmentList.CurrentPageIndex = 0;
       bindGrid();

这二句是Page_Load里面的

   if(!IsPostBack)
   {
    this.dg_shipmentList.CurrentPageIndex = 0;
    bindGrid();   
   }

所以单独提出来.

                        try
                        {
                            checkResult = checkCOShiptoValidate(e, coNo, shiptoNo, thisShipto, out alertResult);
                        }
                        catch
                        {
                            Page_Load(null,null);
                            dg_shipmentList.CurrentPageIndex = 0;
                            bindGrid();
                            checkResult = checkCOShiptoValidate(e, coNo, shiptoNo, thisShipto, out alertResult);
                        }
