问题描述
导出GridView到Excel工作正常但我的问题是当excel打开
文件时，它变成了数字，这可能会导致问题，导致该字段是一个信用
卡号（例如1234567812345678），excel将显示1.23457E + 15，而
实际值变为1234567812345670，这是完全错误的。
我该怎么办
Export GridView to Excel is working Fine But My problem is when excel open the
file, it became numeric, this may cause problem, cause the field is a credit
card number (e.g 1234567812345678 ), the excel will show 1.23457E+15, and the
actual value became 1234567812345670, that is totally wrong.
so what Can I do
