Question

I have a set of expressions representing some formula with some parameters inside. Like:

[parameter1] * [parameter2] * [multiplier]

And many others like this.

I want to use a regular expression so that I can get a list of strings (List<string>) which will have the following inside:

• [paramter1]
• [paramter2]
• [multiplier]

I am not using regular expressions so often; if you have already used something like this I would appreciate if you can share.

Thanks!

Answer 1

This should do it:

\[\w+\]

Using .net:

string s = "[parameter1] * [parameter2] * [multiplier]";
MatchCollection matches = Regex.Matches(s, @"\[\w+\]");

You may want to use a capturing group here: \[(\w+)\], so you have the parameter’s name on Groups[1].
