我有文件C:\Users\Pawel\Documents\DB.sdf
中的數據庫。我如何連接到它?嘗試連接到.sdf數據庫時出現異常
下面的簡單代碼不起作用並生成異常。
代碼:
[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;
}
結果:
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)
我缺少什麼?我應該怎麼做才能正確打開連接?
編輯:
System.NotSupportedException: SQL Server Compact is not intended for ASP.NET development.
大:P
您使用的是SqlCompact嗎?在我看來你正在使用正常的SQL客戶端 – 2011-05-10 18:04:09
