传递字节值throgh serialport [英] Passing byte value throgh serialport

问题描述

我正在尝试通过串口发送数字作为字节，而不是字符串。

我的意思是如果我想发送120，那应该是1字节，而不是2

后跟一个2和一个0.如何可能？

I'm trying to send numbers over the serial port as bytes, not strings.
What I mean is if I want to send a 120, that should be 1 byte, not a 2
followed by a 2 and a 0.How it possible?

推荐答案

如果你使用System.IO.Ports的SerialPort类： http://msdn.microsoft.com/de-de/library/ms143551% 28v = vs.100％29.aspx [ ^ ]

If you use SerialPort class from System.IO.Ports: http://msdn.microsoft.com/de-de/library/ms143551%28v=vs.100%29.aspx[^]

public void Write(
    byte[] buffer,
    int offset,
    int count
)

buffer
    Type: System.Byte[]
    The byte array that contains the data to write to the port.

offset
    Type: System.Int32
    The zero-based byte offset in the buffer parameter at which to begin copying bytes to the port.

count
    Type: System.Int32
    The number of bytes to write.
