Question

我正在尝试从Azure中托管的服务访问公司场所中存在的SQL数据库。这就是我的尝试：

在本地服务器上创建MS SQL数据库
创建示例Web应用程序（Windows Azure云服务）
修改web.config文件以获得正确的SQL连接字符串
使用Azure管理门户中的激活令牌激活Web角色
在本地服务器上安装本地端点
将网络应用程序发布到Azure
使用Web角色和ocal端点创建端点组
启动应用程序
尝试从数据库中获取记录。

尝试使用Azure从数据库中获取记录时出现以下错误：

System.Data.SqlClient.SqlException (0x80131904): 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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)

请帮忙。

Trusted_Connection必须为false。您无法从Azure执行Windows身份验证。

使用Azure上托管的Web应用程序访问本地SQL数据库
