大神帮忙看看,老是报"IndexOutOfRangeException"
下面的插入数据库的操作已经屏蔽掉了,就单单读取近16000条数据就报错,使用文本分隔 还是一样报错!

[解决办法]
索引超出了范围了，。
找到哪行报错的，
[解决办法]
IndexOutOfRangeException
一般是
数组使用的时候，下标超过数组长度
或者字符串
Substring之类的，超过了字符串的长度
等等
类似这样的原因导致的，
不能调试，你可以先注释掉一些行，进行测试，看在哪注释的地方出错的
比如
string[] line = m_streamreader.ReadLine().Split(',');
你使用之前，应该判断line.Length>6你才能使用line[6]
等等
[解决办法]
错误信息 发出来呗..
出错在哪一行
[解决办法]
索引超出了范围了,首先看看有数组或者别的有关索引问题，然后慢慢调试看超出的地方···
（代码太多了，都懒得看）
