查找指定的服务器/实例时出错
看起来您的连接字符串不正确或服务器不可访问.
首先，要确保SQL Server服务正在运行.其他原因可能是错误的连接字符串或某些防火墙阻塞.

在这里，请查看此博客文章以解决问题:异常-错误26-错误定位了指定的服务器实例 [ ^ ]
提供程序:SQL网络接口，错误:26-错误定位服务器/实例... [ ^ ]
未找到指定的SQL Server" o .. [^ ]

Error Locating Server/Instance Specified
Looks your connection string is incorrect or the server is not accessible.
First and foremost make sure that the SQL Server services are running. Other reasons could be, incorrect connection string or some Firewall blockage.

Here, have a look at this blog post to troubleshoot the issue : MSDN Blogs: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified[^]

If needed, look at these one:
Exception - error 26 - Error Locating Server Instance Specified[^]
provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance...[^]
"Specified SQL server not found" o..[^]

是否已使用SQLEXPRESS Instanace安装Sql Server Express Edition ...并选中Fire wall SQL SERVER PORT 1433，则必须在服务器端启用端口.
并检查SQL SERVER实例和服务是否正在运行.

did u install Sql server Express Edition with SQLEXPRESS Instanace... and check Fire wall SQL SERVER PORT 1433 you must enable port in server side.
and check SQL SERVER Instance and service running or not.
