[英]ReadExisting serial port to bytes using C#
I am trying to use ReadExisting method under the serial port. 我正在尝试在串行端口下使用ReadExisting方法。 the method return for me a string.
该方法为我返回了一个字符串。 however I want to convert this data into bytes.
但是我想将此数据转换为字节。
the sender sends me bytes witout encoding. 发送者向我发送未编码的字节。 however when I am trying to use the ReadExisting method and convert it to bytes I am not getting the exact bytes.
但是,当我尝试使用ReadExisting方法并将其转换为字节时,我没有得到确切的字节。 (closer but no all of them are translate it correctly.
(更接近,但并非所有人都能正确翻译。
I tried to use get bytes in Encoding (tried UTF8,ASCII and others) however didn't find the correct one. 我尝试在编码中使用get字节(尝试过UTF8,ASCII和其他),但未找到正确的字节。 how can I know which encoding it does?
我怎么知道它是哪种编码?
private void _serialPort_DataReceived(object sender,
SerialDataReceivedEventArgs e)
{
int BytesToRead = _serialPort.BytesToRead;
if (BytesToRead > 1)
{
string tmpExist = _serialPort.ReadExisting();
SerialInfo _SerialInfo = new SerialInfo();
byte[] tmpData = Encoding.ASCII.GetBytes(tmpExist); //
System.Text.Encoding.ASCII.GetBytes(tmpExist);
}
Thanks 谢谢
I believe the serial port .Encoding property will get you what you are after. 我相信串行端口.Encoding属性将为您提供所需的服务。 It has been a few years, but I think that was it.
已经有几年了,但是我认为就是这样。
