C# 带有SQL LINQ错误的CGI应用程序

我在windows home premium ISS服务器上运行C#CGI应用程序时遇到问题。 我的代码如下：

        Console.Write("Content-Type: text/plain\n\n");
        string conn = "Data Source=|C:\\DB|\\RegisteredUsers.sdf";
        Console.WriteLine(conn); // Added for debugging
        RegisteredUsers userdb = new RegisteredUsers(conn); //DBML file from SqlMetal Here

我得到的错误是：

Data Source=RegisteredUsers.sdf

似乎错误在字符串

conn=@“Data Source=RegisteredUsers.sdf”中或
RegisteredUsers userdb=新的RegisteredUsers（conn）
RegisteredUsers userdb=新的RegisteredUsers（conn）
连接字符串不应是逐字字符串文字；只需删除@符号并用反斜杠转义任何反斜杠。
仍然不起作用。同样的错误。该行现在是：string conn=“Data Source=RegisteredUsers.sdf”；我有没有提到，如果我只是从cmd启动EXE，它就可以正常工作？您好，没有，您没有提到，但是您也尝试过吗？string conn=“数据源=|数据目录| \\RegisteredUsers.sdf”；
