                    return true;
                }
                else
                {
                    return false;
                } 
 

            }

这里for循环没有，只执行一遍，明明有2条数据
求解 asp.net string 数据 path buffer
[解决办法]
可能是你那return返回了吧
[解决办法]
dt2.Rows.Count你的这个是两条么？ 我看你代码里也没怎么用到i 可以使用foreach(DataRow drr in dt2.Rows ){}
[解决办法]
break了吧
[解决办法]
应该是return返回了，循环就不走了。
[解决办法]
可能是return了 楼主打个断点 debug就知道了
[解决办法]
return会跳出循环
