Question

我已将我在vs2010中构建的asp.net网站移至网站主机myasp.net。我试图连接到数据库，但他们的默认连接字符串：

Data Source=SQL5024.myASP.NET;Initial Catalog=MYDBNAME;User Id=MYUSERNAME;Password=YOUR_DB_PASSWORD

不起作用。它抛出了这个错误：

建立与SQL Server的连接时发生与网络相关或特定于实例的错误。服务器未找到或无法访问。验证实例名称是否正确，以及SQL Server是否配置为允许远程连接。（提供程序：SQL网络接口，错误：26 - 查找指定的服务器/实例时出错）

错误消息的其余部分如下：

我已尝试编辑连接字符串以包含服务器和端口，如下所示，但它似乎没有什么区别。

Server=SQL5024.myASP.NET,1433;

我相信网站上的SQL Server版本是2014年。我已经重新创建了我在本地使用的数据库，所以我不明白这是什么问题。我错过了与实例有关的事情吗？

Answer 1

事实证明我需要编辑web.config中的连接字符串以及该页面的后端代码。业余错误，但也许这有助于有类似问题的人。
