Converting Bytes to String results in ? rather than £ (ASCII)

Question

I have pulled a predefined message from a network stream and I convert it to a string using:

string payloadString = System.Text.Encoding.ASCII.GetString(payloadBytes);

I have noticed from reading here: http://www.ascii-code.com/

that £ is only for ASCII extended (127+) and the one I am using above only covers non extended ASCII (0 - 127).

This results in some of my payload containing '?' rather than '£'.

Is there a way of converting the bytes using ASCII Extended encoding?

Thanks.

Answer 1

Use Encoding.Default (which is the system's default ANSI code page) or Encoding.UTF8 , rather than Encoding.ASCII . In any case, check with whoever sends the message what the encoding is supposed to be, and use that.

Answer 2

使用UTF8编码对象将Unicode字符编码为每个字符一到四个字节的序列，这将确保字符的正确编码

string payloadString = System.Text.Encoding.UTF8.GetString(payloadBytes);

Answer 3

更改您的代码：

string payloadString = System.Text.Encoding.UTF8.GetString(payloadBytes);
