Question

我将连接字符串的路径插入数据库（A）。连接数据库（B）的路径使用。当我从数据库（A）中选择该路径并尝试连接数据库（B）时。这是警报信息显示

不支持关键字：＆＃39; @＆＃34;数据来源＆＃39;。＆＃39;

这是数据库（A）中的连接字符串：

@＆＃34;数据源=（LocalDB）\ MSSQLLocalDB; AttachDbFilename = C：\ Users \ it_staff \ source \ repos \ MonitorProduction_Client \ MonitorProduction_Client \ App_Data \ monitorclientdb.mdf; Integrated Security = True＆＃34;

connect_db.conn.Close();
connect_db.conn.Open();
SqlCommand cmd_select_connect_string = new SqlCommand("select board_connect_string from[board] where board_id='" + board_id_[0] + "'", connect_db.conn);
        if (cmd_select_connect_string.ExecuteNonQuery() != 0)
              {
                    SqlDataReader rd = cmd_select_connect_string.ExecuteReader();
                    while (rd.Read())
                    {
                        var board_connect_string = rd[0];
                        connect_db.connb=new SqlConnection(board_connect_string.ToString());  
                    }
                }

只需从数据库中的connect_string

中删除@和两者

Data Source =（LocalDB）\ MSSQLLocalDB; AttachDbFilename = C：\ Users \ it_staff \ source \ repos \ MonitorProduction_Client \ MonitorProduction_Client \ App_Data \ monitorclientdb.mdf; Integrated Security = True
