注意 我试过了

关闭,重新打开Sql server Management Studio.

关闭,重新打开VS和重建解决方案

杀死工人进程访问数据库.

登录凭据是正确的.

能够ping服务器以确保它不会关闭.

对于SQL2008,

打开Management Studio

rt点击实例

去物业

选择安全性

在服务器身份验证下,检查SQL Server和Windows身份验证模式

点击确定

使用配置管理器重启服务器.

原来是某些SQL服务在服务器上以某种方式停止了.手动重新启动SQL Server服务是解决方案.

我知道这是愚蠢的,但无论如何都有效.感谢@PareshJ的有用评论.
