blocks|key|1164439|text|首先，您需要修复字符串的来源。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1164440|.NET中的字符串实际上只是一个由16位unicode代码点和字符组成的数组，因此字符串不采用任何特定的编码。|1164441|当你把这个字符串转换成一组字节时，编码就开始起作用了。|1164442|在任何情况下，如您所见，将字符串编码为具有一个字符集的字节数组，然后使用另一个字符集对其进行解码的方法是不起作用的。|1164443|你能告诉我们更多关于原始字符串来自哪里，以及为什么你认为它被错误编码的原因吗？|1164444|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|M|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|N|8|@]|9|@]|A|$]]|$1|F|3|G|5|6|7|O|8|@]|9|@]|A|$]]|$1|H|3|I|5|6|7|P|8|@]|9|@]|A|$]]|$1|J|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|K|$]]

You need to fix the source of the string in the first place.

A string in .NET is actually just an array of 16-bit unicode code-points, characters, so a string isn't in any particular encoding.

It's when you take that string and convert it to a set of bytes that encoding comes into play.

In any case, the way you did it, encoded a string to a byte array with one character set, and then decoding it with another, will not work, as you see.

Can you tell us more about where that original string comes from, and why you think it has been encoded wrong?

blocks|key|1164537|text|我认为您的问题是，假设表示utf8字符串的字节在解释为其他内容(iso-8859-1)时将产生相同的字符串。但事实并非如此。我推荐你阅读Joel+spolsky的this+excellent+article。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1164538|entityMap|0|LINK|mutability|MUTABLE|url|http://www.joelonsoftware.com/articles/Unicode.html^0|29|M|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

I think your problem is that you assume that the bytes that represent the utf8 string will result in the same string when interpreted as something else (iso-8859-1). And that is simply just not the case. I recommend that you read <a href="http://www.joelonsoftware.com/articles/Unicode.html" rel="noreferrer">this excellent article</a> by Joel spolsky.

Try this:

Use <a href="http://msdn.microsoft.com/en-us/library/system.text.encoding.convert.aspx" rel="noreferrer">Encoding.Convert</a> to adjust the byte array before attempting to decode it into your destination encoding.

<pre><code>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);

blocks|key|1379721|text|看起来有点奇怪的代码。要从Utf8字节流中获取字符串，您需要做的全部工作是：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1379722|string+str+=+Encoding.UTF8.GetString(utf8ByteArray);|code-block|syntax|javascript|1379723|如果您需要将iso-8859-1字节流保存到某个位置，那么只需使用：|1379724|byte[]+iso88591data+=+Encoding.GetEncoding("ISO-8859-1").GetBytes(str);|1379725|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|N|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|O|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

Seems bit strange code. To get string from Utf8 byte stream all you need to do is:

<pre><code>string str = Encoding.UTF8.GetString(utf8ByteArray);
</code></pre>

If you need to save iso-8859-1 byte stream to somewhere then just use:
additional line of code for previous:

<pre><code>byte[] iso88591data = Encoding.GetEncoding("ISO-8859-1").GetBytes(str);
</code></pre>

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:

<pre><code>Encoding iso = Encoding.GetEncoding("ISO-8859-1");
Encoding utf8 = Encoding.UTF8;
string msg = iso.GetString(utf8.GetBytes(Message));
</code></pre>

My source string is

<pre><code>Message = "ÄäÖöÕõÜü"
</code></pre>

But unfortunately my result string becomes

<pre><code>msg = "Ã?Ã¤Ã?Ã¶Ã?ÃµÃ?Ã¼
</code></pre>

What I'm doing wrong here?
