用C#将扩展的ASCII字符写入字符串 [英] Write Extended ASCII Char Into String in C#

问题描述

大家好，

我想将byte []转换为字符串，它可以在以下行中正常工作.

Hello All,

I want to convert byte[] into string, it working correctly with following line.

byte[] byArr= new byte[10];

string ascii =  Encoding.ASCII.GetString(byArr);

但是当char的int值大于127(即扩展的ASCII char)时，与ASCII字符相比，我得到的字符字符串错误.我尝试了许多编码器类，但是每次获得不同的值时，即与ASCII表中的值不同.

请帮助我解决此问题.

But when the char''s int value is greater than 127 (i.e extended ASCII char), then i am getting string with wrong character as compare to ASCII characters. I tried with many encoder classes, but each time i am getting different values i.e. which is not same as values in the ASCII table.

Please help me to solve this issue.

Thanks.

推荐答案

最好使用base64编码: ^ ]

It''s better to use base64 encoding : Convert.ToBase64String Method (Byte[])[^]

^ ]
字节189在iso-8859-1中表示"1/2"(又名"Latin-1")，因此以下可能是您想要的:

Byte 189 represents a "½" in iso-8859-1 (aka "Latin-1"), so the following is maybe what you want:

var e = Encoding.GetEncoding("iso-8859-1");
var s = e.GetString(new byte[] { 189 });

.NET中的所有字符串和字符都是UTF-16编码的，因此您需要使用编码器/解码器来转换其他任何内容，有时这是默认设置(例如，对于FileStream实例为UTF-8)，但是好的做法是始终指定. />
您将需要某种形式的隐式或(更好)显式元数据，以向您提供有关哪种编码的信息.

All strings and chars in .NET are UTF-16 encoded, so you need to use an encoder/decoder to convert anything else, sometimes this is defaulted (e.g. UTF-8 for FileStream instances) but good practice is to always specify.

You will need some form of implicit or (better) explicit metadata to supply you with the information about which encoding.
