Get A Regular Expression That Can Validate That A String Is An Alphanumeric Comma Delimited String?

Jun 23, 2011

I need a regular expression that can validate that a string is an alphanumeric comma delimited string.

Examples:

123, 4A67, GGG, 767 would be valid.
12333, 78787&*, GH778 would be invalid
fghkjhfdg8797< would be invalid

This is what I have so far, but isn't quite right: ^(?=.*[a-zA-Z0-9][,]).*$

Find A Substring In An ArrayList, StringCollection Or List(Of String)

Jun 7, 2010

I've got some code that creates a list of AD groups that the user is a member of, with the intention of saying 'if user is a member of GroupX then allow admin access, if not allow basic access'.

I was using a StringCollection to store this list of Groups, and intended to use the Contains method to test for membership of my admin group, but the problem is that this method only compares the full string - but my AD groups values are formatted as cn=GroupX, etc....

I want to be easily able to determine if a particular substring (i.e. 'GroupX') appears in the list of groups. I could always iterate through the groups check each for a substring representing my AD group name, but I'm more interested in finding out if there is a 'better' way.

Clearly there are a number of repositories for the list of Groups, and it appears that Generics (List(Of String)) are more commonly preferred (which I may well implement anyway) but there is no in-built means of checking for a substring using this method either.

I've settled on using a List(Of), and I've borrowed from Dan's code to iterate through the list.

C# - Prepend A Substring If The Source String Does Not Begin With The Same Substring?

Oct 10, 2011

I'm trying to create a valid RegEx replacement pattern for correctly formatting specific .XML file names. Specifically, if a file name does not begin with a prefix, let's say, ACE_. If the XML file name and extension does not begin with ACE_, prepend the string ACE_ to the file name.For example, if my input source string is the following:

Widgets.xml

I would like to execute a single RegEx Replacement that would result in the string being:

ACE_Widgets.xml.

Conversely, if the string already begins with ACE_, I would like it to remain unchanged. Also,how can I include the pattern ".xml" to ensure that the string pattern for the file name and extension ends with ".xml" in the same matching pattern for the RegEx Replacement pattern? As for the match, I have some luck with the following:

^ACE_{1}[dD]+

Which indicates there is a match for the pattern if the input string is ACE_Widgets.xml and no match if the string is Widgets.xml
The RegEx pattern would suffice, but if you need to know the language in which I'd like to use the replacement pattern is in .NET 4.0 in either C# or VB.NET.

The following posting is close to what Im looking for, but with the inclusion of the *ix directory path prefix, and the use of preg_replace() in PHP, I'm having a bit of a struggle getting it to work with what I need to do:

.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.
