使用SQLite的C＃Web服务

Question

我在C＃中创建了Web服务（将数据添加到SQLite数据库中）。运行项目后，我在Service1.asmx页面上收到此消息

Finisar.SQLite.SQLiteException: Valid parameters:
Data Source=<database file>  (required)

   at WebService3.Service1.addUser(String id, String fname, String lname, String phone, String email, String lag, String log) in d:\MiniProject2013\ConsoleApplication2\WebService3\Service1.asmx.cs:line 53

请建议我做什么
