所以我在Visual Studio 2010中创建了一个MVC3（Razor）网站。现在我想将它发布到服务器，但在我将文件发布并上传到服务器后仍然收到以下错误消息：

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)

我的项目中是否有遗漏的内容？我确信localhost \ sqlexpress的数据源是正确的。

谢谢

我假设您将此发布到不同的服务器，如虚拟私有主机？如果是这样，数据源是sqlexpress是非常奇怪的。

Localhost \ sqlexpress适用于SQLServer Express，它通常安装在开发人员计算机上，如果它位于生产服务器上，您通常会拥有SQLServer Enterprise或其他东西。

如果您使用SQL Server实例提供了正确的数据库连接字符串，则可以重新启动数据库服务器服务。然后再次尝试发布您的网站。请询问它是否对您不起作用。
