我看到了很多有关此错误的问题。但没有一个与形式有关。我在本地测试后托管了我的应用程序服务器。我认为它工作了几分钟,但我不确定,因为我可能已经看了一会儿localhost标签。然后它停止工作。当我在服务器上进行更改时,我可能已经改变了一些东西。“系统找不到指定的文件”
我检查了我的连接字符串,并尝试使用其他方式登录到数据库,它在线。所以,任何线索可能是错的。我不认为有可能sql服务器只响应来自应用程序的请求,并且如果您通过SSMS登录则可用。
下面是我得到的错误。

有人也有过这样的错误,他们说,他们使用了错误的店来连接到数据库,因此错误。我的代码中只有一家商店。没有其他。
更新:
我发现了这个问题。它与会员有关。有些东西与我的会员连接字符串不符。但我不知道是什么。我的应用需要注册才能启用身份验证。我只保留了默认设置。还在App_Data文件夹中发布了mdf文件。 这里有一个类似的问题:Deploying ASP.NET membership to Godaddy。但解决方案并不明确,答案已标出。我加入了 连接字符串和我看到的错误
The connection name 'LocalSqlServer' was not found in the applications configuration or the connection string is empty.
所以,我应该怎么办?这个会员资格在当地是完美无缺的。
更新:
我也试过这是什么人建议Godaddy ASP.NET membership database woes。我删除了conn字符串,并添加了名称“LocalSqlServer”,以使Godaddy快乐。然后我删除并添加以下这个connectionStringName - DefaultProfileProvider,DefaultMembershipProvider,DefaultRoleProvider和DefaultSessionProvider。仍然得到相同的系统错误找不到指定的文件。
web.config中的'defaultConnectionFactory'是什么?我也可能有同样的问题,我相信它与defaultConnectionFactory –
我遇到了几个问题,并解决了所有问题。不知道它是什么,但它与defaultConnectionFactory没有任何关系。我认为这个错误是我在配置中拥有TrustedConnection = true的地方。 – strider
