ANSI vs SHIFT JIS vs UTF-8在c＃中 [英] ANSI vs SHIFT JIS vs UTF-8 in c#

问题描述

我已经有一段时间想找出两者之间的区别了。问题在于使用ANSI编码的文件具有日语字符，例如：，È‚‚Æ‚à1‚‚ÌINCREMENTs‚ª•K-v‚Å，·。相当于shift-jis的是少なくとも1つのINCREMENT行が必要です。可能是日文。

I have been trying to figure the difference for quite sometime now. The issue is with a file that is in ANSI encoding has japanese characters like: ­‚È‚­‚Æ‚à1‚‚ÌINCREMENTs‚ª•K—v‚Å‚·. It equivalent in shift-jis is 少なくとも1つのINCREMENT行が必要です. which is expected to be in japanese.

从网页上的文件（ANSI中）读取后，我需要显示这些字符。 UTF-8中还有一些其他文件显示的字符不正确。我发现很难找出有什么区别，以及如何更改编码以执行正确的操作。.
我使用c＃读取此文件并显示它，如果需要，我还需要将字符串写回到文件中在网络上对其进行了修改。

I need to display these characters after reading from file(in ANSI) on a webpage. There are some other files in UTF-8 displaying characters right not seeing this. I am finding it difficult to figure out whats the difference and how do I change encoding to do right things here.. I use c# for reading this file and displaying it, I also need to write the string back into file if its modified on web. Any encoding and decoding schemas here?

推荐答案

就代码页而言， ANSI（和 Encoding.Default ）基本上仅表示此系统使用的非Unicode代码页-确切地说，哪个代码页取决于系统的配置方式，但取决于西欧系统，很可能是Windows-1252。

As far as code pages are concerned, "ANSI" (and Encoding.Default in .NET) basically just means "the non-Unicode codepage used by this system" - exactly what codepage that is, depends on how the system is configured, but on a Western European system, it's likely to be Windows-1252.

对于该文本所来自的系统， ANSI似乎表示Shift-JIS-因此，除非您的系统具有

For the system where that text comes from, then "ANSI" would appear to mean Shift-JIS - so unless your system has the same code page, you'll need to tell your code to read the text as Shift-JIS.

假设您正在读取带有

Assuming you're reading the file with a StreamReader, there are various constructors that take an Encoding, so just grab a Shift-JIS encoding with Encoding.GetEncoding("shift_jis") or Encoding.GetEncoding(932) and use it to construct your StreamReader.
