Trying to parse an SQL string and pull out the parameters. Ex: "select * from table where [Year] between @Yr1 and @Yr2" I want to pull out "@Yr1" and "@Yr2" I have tried many patterns, but none has worked, such as:
matches = Regex.Matches(sSQL, "@w*")
and
matches = Regex.Matches(sSQL, "@w*")
I'm using the code below to take a string and split it up into an array. It will take: Disney Land and make it two separate elements. If the string contains "Disney Land" then it is one element in the array. Works great, however it adds some empty elements to the array each time. So I just iterate over the elements and remove them if they are empty. Is there a tweak to the code below that will prevent those empty elements from occurring?
Private m_Reg As Regex
m_Reg = New Regex("([^""^s]+)s*|""([^""]+)""s*")
Dim rezsplit = m_Reg.Split(criteria)
I am wanting to take a string of say the following:
Guiness Harp "Holy Moses"
So that in C# or VB get a match set of:
Guiness
Harp
Holy Moses
Essentially it splits on the spaces unless there are quotes around the spaces, then those words between quotes are considered a single phrase.

I am pretty good with perl regular expressions but evidently I am at a loss on why this doesn't work.The code below stores "Person Test" in output variable.
im output As String
Dim userName As String = "Test, Person"
Dim re As New Regex("(w+),s(w+)", RegexOptions.Singleline)
output = re.Replace(userName, "$2 $1")
So why doesn't the following code store "#Test##Person#" in output variable.
Dim output As String
Dim userName As String = "Test, Person"
Dim re As New Regex("(w+),s(w+)")
For Each Match As Match In re.Matches(userName)
output &= "#" & Match.ToString & "#"

I'm using a SortedDictonary(Of String, String) in my application, and I experience a strange sorting behavior. Consider the following code example:[code]I would expect the keys to be sorted as "'A", "'B", "'C", "A", "B", "C", which is what you get when comparing the keys "by hand", through the < operator. And yet, iterating through the keys returns "A", "'A", "B", "'B", "C", "'C".How can I change the SortedDictionary behavior to sort the words beginning with ' first?
View 3 RepliesIt has been a while since I have used regular expressions and I'm hoping what I'm trying to do is possible. I have a program that sends automated response regarding a particular file and I'd like to grab the text between two words I know will never change. In this example those words are "regarding" and "sent"
Dim subject As String = "Information regarding John Doe sent."
Dim name As String = Regex.IsMatch(subject, "")
So in this case I'd like to be able to get just "John Doe". Every regexp I'm coming up with includes the words "regarding" and "sent". How can I use those words as the boundaries but not include them in the match?
[Code] This Regex "^[" + w + "]+$" finds all words which consists of letters "rca". This matches for all words, because all words are made up from "rca". Is there something I could add, to return False for "caar", because "rca" has only one "a", but "caar" has two "a"?

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.
have a regular expression in .NET, which will allow only 24 hr time format in the textbox.

I am trying to validate a csv file of domain names (eg. @google.com, @xyz.co.uk, @xyz.edu etc.) I am using the following Regular Expression:
Regex(@"@(?:[a-zA-Z0-9-]+.)+[a-zA-Z]{2,4}$", RegexOptions.Compiled);
Is there scope for improvement on the above?
Regex(@"@(?:[a-zA-Z0-9-]+.)+[a-zA-Z]{2,4}$", RegexOptions.Compiled);
Using the above, I want to pass only values like @gmail.com, @xyz.edu, @co.uk etc...
