首页 > 解决方案 > 经典的 ASP 文件上传问题

问题描述

我正在尝试上传一个 csv 文件,然后逐行读取它并将其传递给我的数据库。我在文件上传时遇到问题,我可以看到,每当我上传文件时,都会在我的 csv 的列中添加一个额外的数字,因此我的代码会失败。我可以看到文件保存在预期的位置,当我打开它时,我可以看到一个我从未添加过的额外数字。这可能是什么原因?

这是我上传到服务器的 csv 文件,具有额外的价值

这是我上传 CSV 文件并读取它并使用循环的代码,我正在迭代 csv 文件中的值并将这些值存储在我的变量中,然后将其传递给存储在 DB 中的方法。

您可以看到该文件中添加了额外的值,并且代码失败了。每次上传文件时,我都不知道这个值是从哪里来的。我本地机器中的文件没有那个值。任何人都可以帮忙吗?
