Winform统计成功数 失败数


DataTable dt = DBHelper.RunProcTable("up_select_update"); 
            if (dt != null && dt.Rows.Count > 0) 
            { 
                for (int i = 0; i < dt.Rows.Count; i++) 
                { 
                    string mobileid = dt.Rows[i]["mobile"].ToString(); 
                    string productId = dt.Rows[i]["productId"].ToString(); 
//循环取出数据 500条 
  try 
                              { 
                                  //同步操作 
                                  lblText.Text = "正在同步...."; 
                                  string url = "  www.xxx.cn?mobileId=" + mobileid+"&productid="+productId； 
                                Alex.Utility.HttpUtility.Get(System.Web.HttpUtility.HtmlEncode(url),Encoding.UTF8); 
                                    //成功了 +1 记录是哪个渠道号 
                              } 
                              catch(WebException e) 
                              { 
                                  label2.Text = e.Message; 
                                //失败了+记录是哪个渠道号                               } 
} 
如上图 同步总数 = 成功数+失败数 每次运行程序读取500条数据 我不知道怎么统计成功数和失败数 成功数是在同步操作成功了的情况下数量加1 反之失败数量加1
