如何在C＃中使用正则表达式提取两个特殊字符之间的字符串 [英] How to extract the strings between two special characters using Regular Expressions in C#

问题描述

我对正则表达式完全陌生。我需要实现的是，我有一个包含以下字符串的字符串变量，例如，

我的名字是＃P_NAME＃，我已经＃P_AGE＃岁

我需要使用正则表达式提取两个字符串P_NAME和P_AGE（到一个字符串数组或两个字符串变量等）。即字符串以＃开头，以＃结束，我需要提取中间部分。

如何在C＃中使用正则表达式来做到这一点。 / p>

如果我之间也有换行符，该如何提取上面的内容。例如，

我的名字是＃P_NAME＃，\r\n我今年＃P_AGE＃岁。

谢谢

谢谢大家...

以下为我工作...在8个小时后stackoverflow中，我无法发布自己的答案作为答案...：）

  string str =我的名字是＃P_NAME＃，并且\r\n我今年＃P_AGE＃岁； 
 
 MatchCollection allMatchResults = null; 
 var regexObj = new Regex（@＃\w *＃）; 
 allMatchResults = regexObj.Matches（str）; 
  

allMatchResults包含＃P_NAME＃和＃P_AGE＃（即，包含＃个字符）。但是拥有它比不拥有它有助于我的其他逻辑。

谢谢大家。

以下为我工作。 。

  string str =我的名字是＃P_NAME＃，\r In我今年＃P_AGE＃岁 ; 
 
 MatchCollection allMatchResults = null; 
 var regexObj = new Regex（@＃\w *＃）; 
 allMatchResults = regexObj.Matches（str）; 
  

allMatchResults包含＃P_NAME＃和＃P_AGE＃（即，包含＃个字符）。但是拥有它有助于我的其他逻辑

I am totally new to regular expressions. And what I need to achieve is, I have a string variable containing the following string for example,

"My Name is #P_NAME# and I am #P_AGE# years old"

I need to extract the two strings P_NAME and P_AGE using regular expressions (to a string array or two string variables etc). i.e. the string starts with a # and ends with a # and I need to extract the middle part.

How can I do this in C# using Regular Expressions..?

And how can I extract the same above in case I have a new line character in between as well. i.e. for example,

"My Name is #P_NAME# and \r\n I am #P_AGE# years old".

Thanks

Thanks Everyone...

Following worked for me... I cannot publish my own answer as the answer until 8 hours expires in stackoverflow... :)

string str = "My Name is #P_NAME# and \r\n I am #P_AGE# years old";

MatchCollection allMatchResults = null;
var regexObj = new Regex(@"#\w*#");
allMatchResults = regexObj.Matches(str);

'allMatchResults' contains #P_NAME# and #P_AGE# (i.e. including # character). But having it helps my other logics than not having it.
