以下是我的 web.config 文件。我目前正在学习如何自己部署网站，因为我没有找到任何资源来学习如何使用连接到 Azure 数据库的 ADO.NET（实体框架/使用 DB 模型）来部署网站。我创建了一个测试页面，它只是从特定表中获取所有记录。在开发中完美运行。我只是上传了 web.config、default.aspx、default.aspx.cs 和 bin 文件夹。我正在使用 go daddy。不幸的是，我收到一条错误消息，告诉我我没有连接到数据库！谁能帮我？？！！！

以下是我的错误和堆栈跟踪建立与 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。（提供者：命名管道提供者，错误：40 - 无法打开与 SQL Server 的连接）

说明：执行当前 Web 请求期间发生未处理的异常。请查看堆栈跟踪以获取有关错误及其源自代码的位置的更多信息。

GoDaddy 可能正在阻止出站连接。

联系他们的支持，或切换到一个体面的主机。

您是否尝试过配置 SQL Azure 防火墙以允许来自 GoDaddy 服务器的连接？
