C# Substring Alternative - Return rest of line within string after character
(5 answers)
Closed 6 years ago.
I got on url like.
http://EddyFox.com/x/xynua
Need to fetch substring after /x/ what ever string is there.
complex example I faced is :
http://EddyFox.com/x//x/
Here result should be /x/
It can be achieved with substring ,But we need to perform it with regular expression.
This should do it:
string s = "http://EddyFox.com/x/xynua";
// I guess you don't want the /x/ in your match ?=!
Console.WriteLine(Regex.Match(s, "/x/(.*)").Groups[1].Value );
this is probably even better:
Console.WriteLine(Regex.Match(s, "(?<=/x/)(.*)").Value );
the output is
xynua
Have a look at this post: Regex to match after specific characters SO is full of RegEx posts. The probability is very high that a RegEx question has already been asked before. :)
The regex /x/(.*) will capture everything following the /x/
And where is the problem?
var r = new Regex("/x/(\\S*)");
var matches = r.Matches(myUrl);
This regex matches everything from /x/ until the first occurence of a white-space.

Given a filesystem path, is there a shorter way to extract the filename without its extension?

My regex is really poor so I need help with a c# regex expression that can match a substring after the last backslash.
Typical input:
D:\DataFiles\Files_81\aars2016FAKH1800010.pdf
I need to check if the filename aars2016FAKH1A800010.pdf contains "FAKH1". It is important that only the filename is evaluated.
It must be done with C# regex, so please no "Contains"
You might be wondering why regex, but this is going to be used in a generic c# application that can evaluate regex expressions.
Thank you in advance.
You can try to use \\\w*(FAKH)\w*\.pdf pattern.
bool isExsit = Regex.IsMatch(#"D:\DataFiles\Files_81\aars2016FAKH1800010.pdf", #"\\\w*(FAKH)\w*\.pdf");
EDIT
You can use Groups[1].Value get FAKH
var result = Regex.Match(#"D:\DataFiles\Files_81\aars2016FAKH1800010.pdf", #"\\\w*(FAKH)\w*\.pdf");
var FAKH = result.Groups[1].Value;

Returning only part of match from Regular Expression
(4 answers)

I have a responce string
"c=2020&action=approvecomment&_wpnonce=7508ac918a' data-wp-lists='dim:the-comment-list:comment-2020:unapproved:e7e7d3:e7e7d3:new=approved"
Im trying to extract 2020 and 7508ac918a. I dont understand how I must use regex with substrings in C#, simple regex like
c=(\d+)&action=approvecomment&_wpnonce=(.*?)' .+new=approved.
In Regex, you can create match groups
They look like this (?.+?)
So your _wpconce part could become something like this (?.*?)
Then you can grab each group individually for example
Match result = myRegex.Match(someString);
soneOtherString = result.Groups["GROUPNAME"].Value;
I use Regex101 to build and test my regex. (Whoever made that site deserves a crown with shinny stones on it!! :)

How to use string.Endswith to test for multiple endings?

Closed 5 years ago.
I need to check if a string last word is either "...abc" or "...xyz" or "...fgh".
How i can achieve the same thing using regex as i am trying to learn it?
e.g Sentence 1: Hi My Name is abc.
Sentence 2: I live in xyz.
The above sentence is a sample one to demonstrate.
You don't need any Regex. Just use String.EndsWith :
string a = "asdasd abc";
Console.WriteLine(a.EndsWith("abc.") || a.EndsWith("xyz.") || a.EndsWith("fgh."));
You can use this simple regex pattern:
(abc|xyz|fgh)$
Put your possible options between parenthesis separated by pipes. The $ means the end of the string.

Good Result:
$3,597,669On 9-12-2016, the price adjusted to $3,597,669 due to the reason allowed under section 35 of the Ordinance
You should be able to use regular expressions to do this. You can use the Regex.Replace method to run regular expressions on your text. Regular expressions are patterns that a regular expression engine tries to match in input text. I recommend that you take a look at the MSDN article here. You can also take a look at the documentation for the Regex.Replace method here. For example, in order to remove the letter c you could use this snippet of code:
output = Regex.Replace(input, "c", "", RegexOptions.IgnoreCase);
This would replace both lowercase and capital Cs because the ignore case option is turned on.
If it is a standard pattern as what you've told me. Use the following code. It takes everything after the last $ sign.
string str = "|b9-12-2016,¢Xocoak¡LO2A35(2)(b)¡ÓocORe3ao-i|],¢Xa?u¡±o¡±i?¢X$3,597,669On 9-12-2016, the price adjusted to $3,597,669 dueto the reason allowed under section 35(2)(b) of theOrdinance";
var result = str.Substring(str.LastIndexOf('$'));

How to read RegEx Captures in C#

Closed 7 years ago.
First of all sorry about the tittle. Didn't know how to explain it.
This is my code:
string sString = #"docs/horaires/1/images/1"
var PickImage = Regex.Matches(sString, "/horaires/(.*?)/images/");
Console.WriteLine(PickImage[0].Value);
This will print /horaires/1/images/ instead of 1. I tried all the RegexOptions but didn't find the solution in there.
What am I doing wrong here?
This is what you need:
string sString = #"docs/horaires/1/images/1";
var pickImage = Regex.Match(sString, #"/horaires/(.*?)/images/");
if (pickImage.Success)
Console.WriteLine(pickImage.Groups[1].Value);
In your original code, PickImage[0] is a Match object, and Value will return the full match. You want the first captured group, so use match.Groups[1].Value. Note that Groups[0] always contains the full match.
No need to use Matches is you want a single result, use Match instead.
