推荐答案

您使用的连接类型不正确。 SqlConnection用于成长的SQL服务器，不适用于SQL Server Compact。

You're using the wrong type of connection object. SqlConnection is for the grown up SQL server, not for SQL Server Compact.

connectionstrings.com 有您需要的连接字符串。对于连接对象本身，我相信你需要 SqlCeconnection 类

connectionstrings.com has the connection strings you need. For the connection object itself I believe you need the SqlCeconnection class
