.net - Regular Expression Works In VB But Not C#

May 19, 2009

I have the following regular expression for validating a file name:

^(([a-zA-Z]:|))?(((.)|(..)|(. %5D">^/:*?"|<>. |([^/:*?"|<>][^/:*?"|<>. ]))?))). %5D">^/:*?"|<>. |([^/:*?"|<>]*[^/:*?"|<>. ]))?$

I can get it to work in VB.NET but not C#. I can't figure out why it works in one but not the other.

[Code]...

As far as I can tell the patterns are identical in both languages with escaping. When I run the VB code I get a match. When I run the C# code I get nothing.

C# - How Optimise The Regular Expression

Oct 14, 2010

I have just coded the below regular expression. I have a mini rich text editor on a web page (very similar to the one I am using to post this question) and I want to make use of a double asterisk to indicate which words/phrases should be wrapped in a strong tag. The aim is to allow the user to add pre-defined HTML elements without actually having to submit HTML.
[code...]

Maybe I am over-optimising this, but I want to know if this can be made more efficient?

Regular Expression With Filename?

Feb 1, 2012

I have a string (can be anything) and somewhere in the middle of the string there's a filename with the extension 'txt'. The filename can basically be anything, and any filename is correct, but with a certain exception.

If the filename ends with .part<number>.txt, the <number> can only be one of the following, 1, 01, 001, 0001.

Every other <number> is incorrect.

Match
.part1.txt
.Part001.txt

.net - Extract A Particular Value From An INI File Using A Regular Expression?

Dec 22, 2009

I want to extract a URL value from an INI File as such:

[DEFAULT]
BASEURL=http://www.stackoverflow.com/
[InternetShortcut]
URL=http://www.stackoverflow.com/

So I can get the URL value as the only Match from the Regular expression - but I don't understand enough about them (yet) to do this. I have seen RegEx examples that will parse any INI file and get the Name, Value Pairs I just want to get the URL value only from a file no matter what else it contains. My aim is to have something like this:

Dim _pattern As New Text.RegularExpressions.Regex("RegEx")
Dim _url As String = _pattern.Match(iniContentString).Value

It seems simple but I cannot seem to create a specific case RegEx where I want everything from "URL=" to the vbCrLf at the End to be my "Match". I have refered to Regular-Expressions.info which has been a help before but still cannot get this simple example to work.

Building A Dynamic Regular Expression?

Jun 12, 2009

I'm attempting to build a function that will return a regex that is dynamically created.The regex to create will be a range check between two numbers. So far I've got something similar to this (not finished as yet).Is this approach valid, or is there an easier way that I'm overlooking?

Public Shared Function Range(ByVal Minimum As Integer, ByVal Maximum As Integer) As String
Return "^([" & Minimum.ToString.PadLeft(2, "0") & "]" & Microsoft.VisualBasic.StrDup(Minimum.ToString.Length, "[0-9]") & "|2[0-4][0-9]|25[0-5])$"
