连接到在C＃中的Microsoft SQL Server失败

Question

我在运行时出现此错误：

Additional information: 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)

Answer 1

1. 你需要尝试使用SSMS连接到数据库LibraryDB。
2. 您的连接字符串Data Source格式错误且语法不正确。 LocalDB名称后永远不会有HashTag。
3. 您最好使用.（LocalHost）在您的计算机上运行数据库服务器，否则您需要将驱动程序更改为SqlServer以外的其他驱动程序。
