Regexp - Converting From JS Match To C#
Feb 4, 2010
This is probably a simple one for C# people :-) I have this regular expression in javascript:
strVar = strVar.replace(/(specificattribute=)"s*([^"]+?)s*"/g, '$1"$2"');
It replaces leading and trailing spaces inside a specific attribute's value, globally (as per this example page: [URL]). I need to do the same on a string in C#, but when trying the above, the syntax checker chokes at the regExp. So I need the equivalent line of the above in C#.

I am trying to match a username to a userid which are in 2 different sql tables. Here is my select statement:
SELECT aspnet_Users.UserName
FROM aspnet_Users INNER JOIN
aspnet_starterkits_Projects ON aspnet_Users.UserName = aspnet_starterkits_Projects.ProjectManagerId
When I run this i get an error message: "Conversion failed when converting from a character string to uniqueidentifier" Is there anyway around this? Or a different select statement etc?

When validating an email address with the regex validation component, an additional RequiredFieldValidator must be added to ensure there is a value present.
I've mostly taken care of this with a CustomFieldValidator, and taking care of this with Javascript.

I have a longer text and some keywords. I want to highlight these keywords in my text. That is no problem with this code:
private static string HighlightKeywords2(string keywords, string text)
{
// Swap out the ,<space> for pipes and add the braces
Regex r = new Regex(@", ?");
keywords = "(" + r.Replace(keywords, @"|") + ")";
// Get ready to replace the keywords
r = new Regex(keywords, RegexOptions.Singleline | RegexOptions.IgnoreCase);
// Do the replace
return r.Replace(text, new MatchEvaluator(MatchEval2));
}
private static string MatchEval2(Match match)
{
if (match.Groups[1].Success)
{
return "<b>" + match.ToString() + "</b>";
}
return ""; //no match
}
But when the word"tournament" is in the text and the keyword "tour" it becomes <b>tour</b>nament. I want to it to highlight the complete word: <b>tournament</b>.

I want a regex expression which only match extensionless url. In otherwords if an extension is present in url then completely ignore it.
/(.+)/(.+) this will match an URL both with and without extension.

So the case is this:
The user can provide a group of strings for a propert. ex:
DaysNeeded ="Sunday,Tuesday,Friday,Saturday";
In the actual UI, the days of the week are available as check boxes. I'm trying to provide a way so that the user can also set the days needed in the code behind through a property.
Now my query is, which strategy is the best way to execute certain pieces of code that are respective to the days that the user have provided. Meaning, the DaysNeeded property has sunday,Tuesday, Friday and Saturday. Each day has certain piece of code to be executed. If i have to have a forloop with a switch case for each day of the week, i feel it would cost more as i have to run the for loop, the number of days the user has given.
Is there a way that i can run a single code that matches all the set of days the user has given and run the respective code pieces?

I have an ASHX handler or an ASPX page (the problem happens in both cases).
The web client sends a request containing If-None-Match and/or If-Modified-Since headers but context.Request.Headers.Get("If-None-Match") or context.Request.Headers.Get("If-Modified-Since") is null in the handler.
The same script works in my local development machine but it doesn't work in the online machine (both are running IIS7 on Win 2008, .NET 3.5)

Given the code below, how do I compare a List of objects's values with a test value? I'm building a geolocation application. I'll be passing in longitude and latitude and would like to have the service answer back with the location closest to those values. I started down the path of converting to a string, and formatting the values down to two decimal places, but that seemed a bit too ghetto, and I'm looking for a more elegant solution.
public class Location : IEnumerable
{
public string label { get; set; }
public double lat { get; set; }
public double lon { get; set; }
//Implement IEnumerable
public IEnumerator GetEnumerator()
{
return (IEnumerator)this;
}
}
[HandleError]
public class HomeController : Controller
{
private List<Location> myList = new List<Location>
{
new Location {
label="Atlanta Midtown",
lon=33.657674,
lat=-84.423130},
new Location {
label="Atlanta Airport",
lon=33.794151,
lat=-84.387228},
new Location {
label="Stamford, CT",
lon=41.053758,
lat=-73.530979}, ...
}
public static int Main(String[] args)
{
string inLat = "-80.987654";
double dblInLat = double.Parse(inLat);
// here's where I would like to find the closest location to the inLat
// once I figure out this, I'll implement the Longitude, and I'll be set
}

I'm baffled as to why this error keeps popping up all the time....
i've created handlers in IIS7 to map requests for static content.
I've added the following line to my routes:
routes.IgnoreRoute("rest/schema/{file}.xsd");
I've checked that the file is physicly present on the location, yet MVC keeps bitching about not beeing able to find a route. What is the IgnoreRoute for then if it keeps searching?

I have a table in the db with one column containing a URL like http://site.com/users/*/profile.I am given a URL (like http://site.com/users/234/profile) and want to select all the rows in the db that match the url (in this case * is a wildcard).
I was thinking of using Regex to do this, by replacing the * with regex for any character. But am unsure as to what the SQL or LINQ code should be for the selection.

The default validation in MVC 3 is based on jQuery Validation, which I can usually customize with something like:
$.validator.setDefaults({
submitHandler: function() { alert('submitHandler'); },
errorPlacement: function(error, element) {
// do something important here
alert('errorPlacement');
},
errorClass: "error",
errorElement: "input",
onkeyup: false,
onclick: false
})

I have a regular expression
^[a-zA-Z+#-.0-9]{1,5}$
which validates that the word contains alpha-numeric characters and few special characters and length should not be more than 5 characters.
How do I make this regular expression to accept a maximum of five words matching the above regular expression.
