我有一個連接到SQL Server數據庫的控制檯應用程序（託管在同一網絡中的專用win計算機上），使用.Net核心編寫（使用Visual Studio Code），它在Windows上工作得非常好。在Ubuntu/Visual Studio上從.Net Core連接到SqlServer代碼
在Ubuntu上運行Visual Studio代碼的代碼庫無法連接到SQL Server實例，說它無法找到服務器。
我可以ping通SQL Server IP並從中獲得響應。
另外我可以使用1433端口上的telnet連接到SQLServer實例。
另外，我也按照建議從nuget中提取了System.Data.Common和System.Data.SqlClient，並在建議的連接字符串中設置了MultipleActiveResultSets = False。
只是爲了保持完整性，這是試圖連接代碼：
var connection = new SqlConnection(myConnectionString);
connection.Open();
這是堆棧跟蹤：

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.

任何想法？
感謝
你的連接字符串是什麼樣的？您是否使用SQL身份驗證？如果您的連接字符串正在使用Windows身份驗證而不是SQL身份驗證，那麼您可能會遇到問題。 –
我正在使用SQL身份驗證。 「SERVERIP \\ MSSQLSERVER，1433; Database = DBName; User = UIsername; Password = password; MultipleActiveResultSets = False」 –
