正则表达式（.NET）捕获除空间以外的所有内容

Question

I am attempting to use a regular expression with a single capture group to turn the following:

[RuleID("MC304")]
[RuleID("MC 304")]
[RuleID("MC 30 4")]

into this:

[RuleID("MC304")]
[RuleID("MC304")]
[RuleID("MC304")]

I have accomplished this result using this regex101 example but it is pretty rudimentary:

I matched

\[RuleID\("(\w*)\s*(\w*)\s*(\w*)\s*"\)\]

and replaced with

[RuleID("$1$2$3")]

I would like to be able to use non-capturing groups nested inside of a capture group so I can just replace the content inside of the double quotes with $1 instead of having to concatenate $1$2$3 but I don't believe this is possible.

If anyone has any guidance on how to write a regular expression that is more reusable than having to duplicate (\\w*)\\s* for every space I expect I'd greatly appreciate the help!

Edit

I am wanting this solution to be generic for any alphanumeric string with spaces in between. The example above is for "MC304" but it could just as well be any number letter combination with spaces.

Note: I am using Visual Studio's built in find and replace feature to remove spaces from all RuleID attributes across the entire solution.

After clarifications in the comments on the usage, you can use this pattern to match your strings. Note that you need to provide the length (without spaces) of your search string, and the search string itself (again without the spaces).

([mc304](?:\s+?)?){5}

This works by using a non capturing group to isolate spaces, and by using a character class to specify which characters are legal. Note that you should not be repeating letters or numbers in there, so if you are looking for "mc300", you would use [mc30] and a length of 5. Unfortunately this will also match mc030 and mc003 etc... But maybe you can work with that by making sure manually before pressing replace...
