Using Regex to remove css comments

How can I remove comments from CSS using Regex.Replace()?

Note - I'm not able to use the regex mentioned here in C# - Reg开发者_Python百科ular expression to remove CSS comments.

That would be normally enough (assuming cssLines is a string containing all lines of your CSS file):

 Regex.Replace(cssLines, @"/\*.+?\*/", string.Empty, RegexOptions.Singleline)

Please note that the Singleline option will allow to match multi-line comments.

Use the regex from the linked question like so:

var rx = new Regex(@"(?<!"")\/\*.+?\*\/(?!"")");

I wonder if the following version of Maxim's solution would be faster.

"/\*[^*]*.*?\*/"

As the discussion shows this will also eliminate comments within string literals.

Very late reply but thought it will be useful for some

"(?:/*(.|[\r\n])?/)|(?:(?([^)])//.)"

This will help removing css comments both singleline and multiline.
