Why is this Regex not working on MVC unobtrusive validator?

Question

I have the folowing regex on my MVC view model (p.s. all other regex`es work fine)

[Required, MaxLength(256)]
[RegularExpression(@"/(\[Brand name\])/i", ErrorMessage = "Reply message <strong> Must</strong> contain <strong>[Brand name]</strong>")]
public string ReplyMessage { get; set; }

enter image description here

.NET regex pattern strings do not require (and must not have) regex delimiters. So instead of: `@"/(\[Brand name\])/i"` use: `@"(?i)(\[Brand name\])"`. — ridgerunner, Aug 28 '13 at 14:22

Unless I'm misunderstanding the need, the regex should be:

.*(\[Brand name\]).*

Or in other words, any character before and after, but must contain "[Brand name]".

OK, seems to be working, but wont accept any options.. If I add it like this "/.*(\[Brand name\]).*/i" doesn't – Marty Aug 28 '13 at 14:05
@Marty, you don't technically need the ending wildcard, try removing it and see what happens. – Mike Perrenoud Aug 28 '13 at 14:08
@Marty Does .NET allow you to create your regex using `//` delimiters ?!! – Ibrahim Najjar Aug 28 '13 at 14:21
@Sniffer, those Regex's are used in JavaScript. – Mike Perrenoud Aug 28 '13 at 14:24
I think this is C# he is using. – Ibrahim Najjar Aug 28 '13 at 14:29
@Sniffer, those Regex's are applied in JavaScript by the MVC framework. – Mike Perrenoud Aug 28 '13 at 14:32
I tried this approach, but it didn't help http://stackoverflow.com/questions/4218836/regularexpressionattribute-how-to-make-it-not-case-sensitive-for-client-side-v – Marty Aug 28 '13 at 15:23
