C＃将字符串从UTF-8转换为ISO-8859-1（Latin1）H [英] C# Convert string from UTF-8 to ISO-8859-1 (Latin1) H

问题描述

基本上我需要转换UTF-8字符串到ISO-8859-1，我使用以下代码：

 编码iso = Encoding.GetEncoding（ISO-8859- 1\" ）; 
编码utf8 = Encoding.UTF8; 
 string msg = iso.GetString（utf8.GetBytes（Message））; 
  

我的源字符串是

  Message =ÄäÖöÕõÜü
  

但不幸的是，我的结果字符串变成

  msg =Ã？Ã？ pre> 
 
 
我在这里做错什么？
解决方案
使用 Encoding.Convert 以调整字节数组之前尝试将其解码为目标编码。
 编码iso = Encoding.GetEncoding（ISO-8859-1）; 
编码utf8 = Encoding.UTF8; 
 byte [] utfBytes = utf8.GetBytes（Message）; 
 byte [] isoBytes = Encoding.Convert（utf8，iso，utfBytes）; 
 string msg = iso.GetString（isoBytes）; 
  
 
I have googled on this topic and I have looked at every answer, but I still don't get it.

Basically I need to convert UTF-8 string to ISO-8859-1 and I do it using following code:
Encoding iso = Encoding.GetEncoding("ISO-8859-1");
Encoding utf8 = Encoding.UTF8;
string msg = iso.GetString(utf8.GetBytes(Message));
My source string is
Message = "ÄäÖöÕõÜü"
But unfortunately my result string becomes
msg = "�ä�ö�õ�ü
What I'm doing wrong here?
解决方案
Use Encoding.Convert to adjust the byte array before attempting to decode it into your destination encoding.
Encoding iso = Encoding.GetEncoding("ISO-8859-1");
Encoding utf8 = Encoding.UTF8;
byte[] utfBytes = utf8.GetBytes(Message);
byte[] isoBytes = Encoding.Convert(utf8, iso, utfBytes);
string msg = iso.GetString(isoBytes);
