我知道这已经问过！

我用Google搜索这个话题，我已经看过所有的答案，但我还是不明白这一点。

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

基本上我需要为UTF-8字符串转换为ISO-8859-1和我用下面的code的：

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

My source string is

Message = "ÄäÖöÕõÜü"

但不幸的是我得到的字符串变成

But unfortunately my result string becomes

msg = "�ä�ö�õ�ü

我在做什么错在这里？

What I'm doing wrong here?

感谢您的回答，我很抱歉，如果我要求明显。

Thank You for your answers and I'm sorry if I'm asking obvious.

推荐答案

使用Encoding.Convert试图德丙它$ C $进入你的目的地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);
