问题描述

我正在做一个学校项目。这个项目是用C＃窗体，实体框架和SQL Server 2008构建的。我想知道是否有人想检查项目运行的开始，数据库文件是否正确附加到项目，我们如何做到这一点使用C＃或实体框架。

推荐答案

有多种方法可以检测哪些服务器/ SQL服务可用，但我建议您尝试执行一些查询/ catch并检查任何异常。您很快就会发现无法连接到SQL服务器的那个。然后你知道它不可用。



听起来怎么样？

There are ways to detect what servers / SQL services are available, but I'd suggest you try to perform some query with a try/catch and check any exceptions. You'll soon find the one that says "unable to connect to SQL server". Then you know it's unavailable.

How does that sound?
