如何解决经典的ASP文件上传问题
我正在尝试上传一个 csv 文件，然后逐行读取它并将其传递到我的数据库。我在文件上传时遇到问题，我可以看到，每当我上传文件时，都会将一个额外的数字添加到我的 csv 列中，因此我的代码失败。我可以看到文件被保存在预期的位置，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 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，然后将这些值传递给存储在 DB 中的方法。>

您可以看到文件中添加了一个额外的值并且代码失败。每次上传文件时，我都不知道这个值来自哪里。我本地机器中的文件没有那个值。有人可以帮忙吗？
