Question

我在本地有一份asp.net mvc网站的工作副本。我刚将整个网站上传到我的网络托管服务器。一切看起来都不错，但是当我登录时，我收到以下错误：

System.ArgumentException：不支持关键字：'provider'。

有什么建议吗？

Answer 1

此MSDN article包含SqlConnection对象的ConnectionString中所有允许的关键字值。 “提供者”不在列表中。

您有两种选择：

删除“provider”关键字;
使用OleDbConnection代替SqlConnection。

Answer 2

为此提供的价值连接字符串可能是错误的，或者它可能包含无效的语法。

我的建议是修复配置字符串。

Answer 3

此外，当您的连接字符串参数“User ID”使用该空格时，如果它被写为“UserID”，那么它也会给出错误

Answer 4

从连接字符串中删除"Provider=MSDORA"。然后这应该有效。

Answer 5

在连接字符串中监视需要空格的关键字。与User ID相同，但UserID会失败。

System.ArgumentException：不支持关键字：'provider'
