我必须在web.config中做出哪些更改才能解决此错误？

Answer 1

IT似乎在web.config中有两次dataConfiguration（这就是“Parser错误消息：已经定义了部分或组名'dataConfiguration'”错误意味着）。

否则，如果没有在此处发布的完整web.config（当然没有敏感信息），则无法知道。

修改：其他可能性：

你有2个web.configs，这是如果你当前的网站是可能的托管在虚拟目录下主要网站。
你改变了中的 machine.config C：\ WINDOWS \ microsoft.net \框架\ V2.0.50727 \ CONFIG 夹

Answer 2

dataConfiguration部分有问题。您是否添加了一些未报告的标签？

Answer 3

在web.config文件中，有时我们错过了正确关闭标记或错过了关闭“AppSetting”标记中的引号。对于前者在此标记中，我错过了正确关闭value属性的引号。

web.config中出错
