亲爱的大家， 我目前正在使用C ++/CLI与串行端口通信，但是使用此方法时会遇到一些问题. 在您完成数据读取之前，我不确定如何应用StreamWriter函数将数据从串行端口缓冲区读取到文本文件中吗? 有人可以帮助您阅读示例代码吗? 我以前写过一些代码，但是它有几个程序，我不知道为什么.

Dear guys, I am currently using C++/CLI to communicate with serial port, but I encounter some problems when using this method. I am not sure how to apply StreamWriter function to read data from the serial port buffer into a text file until you the data reading finish? can anybody help to read a sample code? I previously write some code, but it has severial programs and i donot know why.

//create a instance of streamwriter to write text into file StreamWriter^ sw = gcnew StreamWriter("data.txt", true); DataReceiving = gcnew System::IO::Ports::SerialPort::ReadLine(); sw->WriteLine("you can use write function !!!"); sw->Close(); Console::WriteLine("Type QUIT to exit");

非常感谢您的帮助.

many thanks for your help.

推荐答案

您是否正确配置了端口? 与此类似的东西应该可以工作: Did you configure your port properly? Somthing close to this should work: //configure port SerialPort^ port = gcnew SerialPort(); port->PortName = "COM1"; port->BaudRate = 9600; port->DataBits = 8; port->Parity = Parity::None; port->StopBits = StopBits::One; port->ReadTimeout = 500; port->WriteTimeout = 500; //don''t forget this if you want to handle characters above 0x7f port->Encoding = System::Text::Encoding::GetEncoding("Latin1"); //read data from port String^ txt = port->ReadExisting(); //write txt to file StreamWriter^ sw = gcnew StreamWriter("TestFile.txt"); sw->WriteLine(txt); //you may also call Flush if you don''t want to close the file immediately. sw->Flush(); sw->Close();

只需正确阅读自己的文字即可看到您的困惑: 要读取的StreamWriter函数".和作家一起读书吗?好吧... 其他一切都很容易，我会保证:).

Just read properly your own words to see your confusion: "StreamWriter function to read". Reading with the Writers? Well... Everything else is easy, I''ll guarantee that :).
