新手 报错说结构或接口成员声明种的标记无效 SerialPort serialPort1 = new SerialPort("COM1", 19200, Parity.Odd, 8,StopBits.One); serialPo

Question

然后就报错，说类，结构或接口成员声明种的标记（无效，这个是个什么问题啊，我遇到了很多呢，我是个新手，希望大家不吝赐教。谢谢了

 SerialPort   serialPort1   =   new   SerialPort(); 
                        //更改参数 
                        serialPort1.PortName   =   "COM1 "; 
                        serialPort1.BaudRate   =   19200; 
                        serialPort1.Parity   =   Parity.Odd; 
                        serialPort1.StopBits   =   StopBits.Two;                         //上述步骤可以用在实例化时调用SerialPort类的重载构造函数 
                        //SerialPort   serialPort   =   new   SerialPort( "COM1 ",   19200,   Parity.Odd,   StopBits.Two);                         //打开串口(打开串口后不能修改端口名,波特率等参数,修改参数要在串口关闭后修改) 
                        serialPort1.Open();                         //发送数据 
                        SendStringData(serialPort1); 
                        //也可用字节的形式发送数据 
                        //SendBytesData(serialPort1); 
                        
                        //开启接收数据线程 
                        ReceiveData(serialPort1);
