将文件中的十六进制值转换为行终止符 [英] Converting hex value in a file to a line terminator

问题描述

我正在从客户导入文件.当我在Ultra Edit中打开它时，会看到一个十六进制85，它对于行终止符显示为….我正在尝试将其转换为十六进制0A. Windows理解的任何内容都可以，但是0A在我们的许多其他通信中很常见.我在StreamReader上使用.Replace替换值，但是输出不是我期望的.

将"\ u0085"替换为"\ u000a"会导致…被�替换，该字符在十六进制中表示为EF BF BD.

用"\ x0a"替换"\ x85"具有相同的结果.

对我在做什么错有任何想法吗?非常感谢您的帮助！

//File =原始文件的路径
字符串文件=文件;

//存档=放置新文件的路径
字符串存档=存档

FileInfo fi =新的FileInfo(file);
字符串名称= fi.Name;

StreamReader sr =新的StreamReader(file);
StreamWriter sw =新的StreamWriter(存档+名称);

//下面两行都将产生一个十六进制的EF BF BD，该文本在文本中显示为…
//字符串输入= sr.ReadToEnd().Replace("\ x85"，"\ x0a");
字符串输入= sr.ReadToEnd().Replace("\ u0085"，"\ u000a");

sw.Write(input);
sr.Close();
sw.Close();

I''m importing a file from a customer. When I open it up in Ultra Edit is see a hex 85 which shows up as … for the line terminator. I''m trying to convert it to a hex 0A. Anything that windows understands would be fine but 0A is common in many of our other communications. I''m using a .Replace on a StreamReader to replace the value but the output is not what I expect.

Replacing "\u0085" with "\u000a" results in … being replace by � which is represented in the hex as EF BF BD.

Replacing "\x85" with "\x0a" has the same results.

Any thoughts about what I''m doing wrong? Help is greatly appreciated!

// File = Path of original file
String file = File;

// Archive = Path where new file is to be placed
String archive = Archive

FileInfo fi = new FileInfo(file);
String name = fi.Name;

StreamReader sr = new StreamReader(file);
StreamWriter sw = new StreamWriter(archive + name);

// Both lines below result in a hex EF BF BD which shows up as … in the text
// String input = sr.ReadToEnd().Replace("\x85", "\x0a");
String input = sr.ReadToEnd().Replace("\u0085", "\u000a");

sw.Write(input);
sr.Close();
sw.Close();

EF BF BD是UTF-8(MBCS)字节流的签名.您可能会发现更容易将文件读入内存，然后通过手动搜索Unicode''\ u0085''字符进行替换.

EF BF BD is the signature of a UTF-8 (MBCS) byte stream. You may find it easier to read the file into memory and then do the replacements by searching for the Unicode ''\u0085'' characters manually.

应为:
字符串输入= sr.ReadToEnd().Replace("\ uFFFD"，"\ x0A");

It should be:
String input = sr.ReadToEnd().Replace("\uFFFD", "\x0A");
