正则表达式从字符串中删除\t \r \ n [英] Regex to remove \t \r \n from string

问题描述

我想从我的字符串中删除一些字符（\t

\ r \ n，这些字符串在整个字符串中），我知道正则表达式可以做到这一点，但我

不知道怎么做。任何指针都非常赞赏。


克里斯

Hi, i would like to remove a number of characters from my string (\t
\r \n which are throughout the string), i know regex can do this but i
have no idea how. Any pointers much appreciated.

推荐答案

Chris，


为什么不在String类上使用三次调用Replace方法呢？

string myString = input.Replace（" \t"，" "）。替换（" \r"，""）。替换（" \ n"，

""）;


如果您愿意，也可以在这里使用角色版本。

Chris,

Why not just use three calls to the Replace method on the String class?

string myString = input.Replace("\t", "").Replace("\r", "").Replace("\n",
"");

You can use the character version here as well if you wish.

为什么不在String上使用三次调用Replace方法class？


我目前正在使用3个替换调用:)，但是我总是

避免使用reglular表达式之前这似乎是理想的借口

学习它们！我也有兴趣将字符串中的\\ n转换为

也只是\ n。我肯定一定有可能吗？

avoided reglular expressions before this seemed the ideal excuse to

just \n also. im sure it must be possible?

当然，只是想知道为什么你不会采取更简单，更多的

可维护（取决于谁在看它，至少从我的观点来看）b $ b视图）方法。 =）


在这种情况下，我相信你可以有一个正则表达式[\\\\\ n] \\ n>

然后调用Replace方法，传递你的输入字符串和一个空的

with）它应该工作。

Absolutely, just wondering why you wouldn''t take the simpler, more
maintainable (depending on who is looking at it, at least from my point of
view) approach. =)

In this case, I believe you can have a regular expression of "[\t\r\n]"
and then call the Replace method, passing your input string and an empty
string (or whatever you want to replace any of the characters in that set
with) and it should work.
