How to crop strings using regular expressions? [closed]

-6

Here's the phrase I'd like to convert.

Summoner1 joined the lobby.

Summoner2 jonied the lobby.

Summoner3: Top

Summoner4: ADC

I wanna pick up these words Summoner1, Summoner2, Summoner3, Summoner4.
I suppose I should detect the strings "joined the lobby", and ": " using regular expression(regex) but I have no clue how to.

Thank you in advance.

Codes for extra question.
var list = @"Summoner1 joined the lobby. Summoner2 jonied the lobby. Summoner3: Top Summoner4: ADC"; var result = string.Join("|", list.Select(x => Regex.Replace(x, "( |:).*", string.Empty)));

If you want to use Regex, you can use the following.

"( |:).*"

Example,

var list= @"Summoner1 joined the lobby.

Summoner2 jonied the lobby.

Summoner3: Top

Summoner4: ADC";





var result = list.Split(new {Environment.NewLine},StringSplitOptions.RemoveEmptyEntries).Select(x=> Regex.Replace(x,"( |:).*",string.Empty));

Update: Based on Comment

var result = string.Join("|",list.Split(new {Environment.NewLine},StringSplitOptions.RemoveEmptyEntries).Select(x=> Regex.Replace(x,"( |:).*",string.Empty)));

Output

Summoner1|Summoner2|Summoner3|Summoner4

thank you for your answer so very much. Would you be so kind as to answer the following question? I want it to be in the same line like Summoner1|Summoner2|Summoner3|Summoner4 to be able to use regex multiple matches.

you mean the input string would be in mentioned format or result ?

yeah the latter one. the result.

@XHSKR I have updated the answer for you, you can use string.Join for the purpose.
