正则表达式匹配字符串 [英] Regex to match string

问题描述

大家好，

请帮我找到正则表达式：

我的价值如下：''Martin Lucas''

和我的输入字符串是：''我的名字是Martin Lucas，我​​和ABC先生一起工作'。

现在我必须匹配是否名称''Martin Lucas''存在于给定的字符串中。

请建议正则表达式



之前我正在使用



@（^ | \ s）+ mentioned_profilename + @（\ s | $）



这是我的正则表达式..它工作正常。但不能匹配值以''结束'，''

例如，如果以下是我的字符串

你好@Nagsdada KumarDada，@ Vishal Shimpi和@Hatim Jawad 

这个@Nagsdada KumarDada没有得到匹配

解决方案

一个正则表达式可能是矫枉过正：string.Contains方法也会这样做。

但正则表达式非常非常简单：

 Martin Lucas 

或可能

 Martin \ + + Lucas 

但是为了真正的准确性：

（？< = \\\ ）Martin\s +卢卡斯（？= [\s。？'）！]）

Hi all,
Please help me to find regex:
I have value like: ''Martin Lucas''
and my input string is : ''My name is Martin Lucas, i am working with Mr ABC''.
now i have to match whether the name ''Martin Lucas'' is exist in given string.
please suggest the regular expression

previously i was using

@"(^|\s)" + mentioned_profilename + @"(\s|$)"

this in my regex.. it was working fine. but can not match the value ends with '',''
eg if following is my string

hello @Nagsdada KumarDada, @Vishal Shimpi and @Hatim Jawad

in this @Nagsdada KumarDada was not getting match

A regex is probably overkill: the string.Contains method would do it as well.
But the regex is very, very simple:

Martin Lucas

or possibly

Martin\s+Lucas

But for real accuracy:

(?<=\s)Martin\s+Lucas(?=[\s,.?'")!])
