翻译字符串，以自己的实际值 [英] Translate string literals to their actual values

问题描述

注意：我不想做的问题太长，所以如何从问题的标题翻译成有没有在.NET Framework以这种方法。

只是一个提醒：

  \\\
 
  

如果上述是字符串的打印表示，则其内部的版本是一个字符，而不是两个，该代码是0x0A的

不过，我可以写：

 字符串s =\\ \\
;在编辑
 //三个字符 

这相当于2个字符内部表示 \\ \\ 和 N 。这不是0x0A的性格！

不过，我想实现这一目标。即我已经在字符串的一些数据，我知道是一个字符串的打印表示。我想将其转换为内部表示（东西C＃编译器完成所有的时间）。

 字符串可打印=\ \\\
; 
串INTERNAL_ =转换（打印）; 
  

内部_ 现在将举行只有一个字符， 。代码的0x0A

问：（！）？有准备使用功能，例如转换

< DIV CLASS =h2_lin>解决方案

您可以尝试使用的 System.Text.RegularExpressions.Regex.Unescape 静态方法：

 字符串INTERNAL_ = Regex.Unescape（打印）; 
  

但不幸的是它主要适用于正则表达式控制字符。

测试：

  VAR字符= internal_.ToCharArray（）; 
  

的

字符阵列与代码1元的0x0A 。

NOTE: I didn't want to make the question too long, so "how" from the question title translates into "is there a method for this in .Net framework".

Just a reminder:

\n

if the above is printable representation of the string, then its internal version is one character, not two, which code is 0x0a.

However I could write:

string s = "\\n"; // three characters in editor

which translates to internal representation of 2 characters \ and n. This is not 0x0a character!

But I would like to achieve this. I.e. I have already in string some data, which I know is printable representation of a string. And I would like to convert it to internal representation (something C# compiler does all the time).

string printable = "\\n";
string internal_ = convert(printable);

internal_ would hold only one character now, of code 0x0a.

Question: is there ready to use (!) function for such conversion?

解决方案

You could try to use the System.Text.RegularExpressions.Regex.Unescape static method:

string internal_ = Regex.Unescape(printable);

But unfortunately it applicable mainly for Regex control characters.

Test:

var chars = internal_.ToCharArray();

The chars array has 1 element with code 0x0a.
