双引号字符串替换在C＃ [英] Double quote string replace in C#

问题描述

如何更换下面的字符串在C＃

电流：

 约翰KGEN格雷格
  

目标：

 约翰ķ\GEN\格雷格
  

这是错误的，因为我不是逃避它正确：

  S = s.Replace（ ，\）; 
  

什么是语法与替换引号\（斜线）？

任何帮助，将不胜感激。

感谢

解决方案

  S = s.Replace（\，\\\）; 
  

或

  S = s.Replace（@，@\，​​）; 
  

在第一个例子中的有可以用一个反斜杠转义，因为它本来结束的字符串。同样，在替换字符串 \\ 需要通过转义转义字符以产生一个反斜杠。

在第二个例子中逐字字符串时，它们被写成 @...。在这些文字不转义序列的认可，让您编写包含很多个反斜杠在一个更清洁的方式（比如正则表达式）字符串。的作品有唯一的转义序列，的一个。

How to replace the below string in C#

Current:

"John K "GEN" Greg"

The Goal:

 "John K \"GEN\" Greg"

This is wrong because I'm not escaping it properly:

s = s.Replace(""","\"");

What is syntax for replacing quotes with \ (slash)?

Any help would be appreciated.

Thanks

解决方案

s = s.Replace("\"", "\\\"");

or

s = s.Replace(@"""", @"\""");

In the first example the " has to be escaped with a backslash as it would otherwise end the string. Likewise, in the replacement string \\ is needed to yield a single backslash by escaping the escape character.

In the second example verbatim string literals are used, they are written as @"...". In those literals no escape sequences are recognized, allowing you to write strings that contain lots of backslashes in a much cleaner way (such as regular expressions). The only escape sequence that works there is "" for a single ".
