我在 ASP.Net 4.0 框架中创建了一个 Web 应用程序，并使用 MS-SQL 进行数据库交互。我已经构建了我的代码并上传到我的共享网络托管服务器上。它的主页工作正常，并且页面内容不与数据库交互的所有页面工作正常。但是哪些页面与数据库交互这些页面给了我错误：

如何解决共享服务器上的此错误？
所有代码在我们的本地 IIS 服务器和我们的测试专用服务器上都可以正常工作，但我们的客户购买了共享服务器并希望在共享服务器上运行。
此问题类似于发布在共享虚拟主机服务器上的“应用程序尝试执行安全策略不允许的操作”上的线程
但它的解决方案是针对带有 ASP.NET 的 LINQ。我需要用 ASP.NET 解决 MSSQL
