Sql server System.ArgumentException:不支持关键字：'；供应商'；

我在本地有一个asp.net mvc站点的工作副本。我刚刚把整个网站上传到我的主机服务器上。开始时一切看起来都很好，但当我登录时，出现以下错误：

System.ArgumentException:不支持关键字：“提供者”。

有什么建议吗

为提供的值 连接字符串可能错误，或者 可能包含无效语法

我的建议是修复配置字符串。

这包含SqlConnection对象的ConnectionString中允许的所有关键字值。“提供者”不在列表中

您有两个选择：

• 删除“提供者”关键字
• 使用替代SqlConnection的连接

---

从连接字符串中删除

“Provider=MSDORA”

。然后这应该会起作用。

当您的连接字符串参数“User ID”使用空格时，如果它被写为“UserID”，那么它也会出现错误。

注意连接字符串中需要空格的关键字。Like

UserID

是正确的，但是

UserID

将失败
