C＃ - Firebird获取更多错误信息

Question

        string conString = "User=SYSDBA;Password=masterkey;Database=C:\\Users\\dev1\\Desktop\\testdb.fdb;Dialect=3;Charset=UTF8;ServerType=1;";
        FbConnection fcon;

        try
        {
            fcon = new FbConnection(conString);
            string query = "create table test( name varchar(40) );";
            FbCommand cmd = new FbCommand(query, fcon);
            cmd.ExecuteNonQuery();
        }
        catch (Exception e)
        {
            string errstr = e.Message.ToString();
            System.Console.WriteLine("Error: " + errstr);

        }

我只收到错误消息“连接必须有效且打开”;如何确定无法正确建立连接的原因？

您需要致电fcon.Open()打开连接。
