我有文件C:\Users\Pawel\Documents\DB.sdf
中的数据库。我如何连接到它?尝试连接到.sdf数据库时出现异常
下面的简单代码不起作用并生成异常。
代码:
[WebMethod]
public String TestCon()
{
SqlConnection sql = new System.Data.SqlClient.SqlConnection(
@"Data Source=C:\Users\Pawel\Documents\DB.sdf");
string str = "OK";
try
{
sql.Open();
sql.Close();
}
catch (Exception ex)
{
str = ex.Message;
}
return str;
}
结果:
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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
我缺少什么?我应该怎么做才能正确打开连接?
编辑:
System.NotSupportedException: SQL Server Compact is not intended for ASP.NET development.
大:P
您使用的是SqlCompact吗?在我看来你正在使用正常的SQL客户端 – 2011-05-10 18:04:09
