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

我在谷歌上搜索过这个话题，也看过每一个答案，但我还是没明白.

I have googled on this topic and I have looked at every answer, but I still don't get it.

基本上我需要将 UTF-8 字符串转换为 ISO-8859-1 并且我使用以下代码进行:

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));

我的源字符串是

Message = "ÄäÖöÕõÜü"

但不幸的是我的结果字符串变成了

But unfortunately my result string becomes

msg = "�ä�ö�õ�ü

我在这里做错了什么?

推荐答案

使用 Encoding.Convert 在尝试将其解码为目标编码之前调整字节数组.

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);
