串口字节到ASCII

Question

我正在从c＃上的串行端口接收字节，并且将它们存储在字节数组中，然后将它们制成字符串，所以现在我需要将字节转换为ASCII，我该怎么做？这是我的代码

void DataReceivedHandler（对象发送者，SerialDataReceivedEventArgs e）     {

    string bytestr = "";

    int numbytes = serialPort1.BytesToRead;
    byte[] rxbytearray = new byte[numbytes];



    for (int i = 0; i < numbytes; i++)
    {
        rxbytearray[i] = (byte)serialPort1.ReadByte();

    }

    string hexvalues = "";
    foreach (byte b in rxbytearray)
    {
        if (b != '\r')
            hexvalues = hexvalues + (b.ToString()) + " ";



    }       //  hexvalues = richTextBox1.Text;

    Thread.Sleep(500);

    MessageBox.Show(hexvalues);



}

Answer 1

Encoding.ASCII.GetString(byteArray);

Answer 2

我会这样：

use std::cell::RefCell;

struct Wrapper {
    data: RefCell<struct_from_c_t>,
}

impl Wrapper {
    fn do_thing(&self) {
        unsafe { ffi_fn(&mut *self.data.borrow_mut()) }
    }
}
