连接字符串本地数据库中的错误与c＃ [英] error in connection string local database with c#

问题描述

我使用vs2010创建了本地数据库并将其附加到新项目vs2010（Microsoft SQL Server Compact 3.5）



现在我收到连接字符串错误

i created local database with vs2010 and attached it with new project vs2010 as ( Microsoft SQL Server Compact 3.5)

now i get error with connection string

"Data Source=|DataDirectory|/Database.sdf"

建立与SQL的连接时发生网络相关或特定于实例的错误服务器。服务器未找到或无法访问。验证实例名称是否正确，以及SQL Server是否配置为允许远程连接。 （提供者：命名管道提供者，错误：40 - 无法打开与SQL Server的连接）





任何想法

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)


any idea
