I need a Regular Expression to capture ALL comments in a block of T-SQL. The Expression will need to work with the .Net Regex Class.
Let's say I have the following T-SQL:
-- This is Comment 1
SELECT Foo FROM Bar
GO
-- This is
-- Comment 2
UPDATE Bar SET Foo == 'Foo'
GO
/* This is Comment 3 */
DELETE FROM Bar WHERE Foo = 'Foo'
/* This is a
multi-line comment */
DROP TABLE Bar
I need to capture all of the comments, including the multi-line ones, so that I can strip them out.
EDIT: It would serve the same purpose to have an expression that takes everything BUT the comments.

We use regular expressions to define specific patterns in T-SQL in a LIKE operator and filter results based on specific conditions. We also call these regular expressions as T-SQL RegEx functions. In this article, we will use the term T-SQL RegEx functions for regular expressions.
Comments can be inserted on a separate line or within a Transact-SQL statement. Multiple-line comments must be indicated by /* and */. A stylistic convention often used for multiple-line comments is to begin the first line with /*, subsequent lines with **, and end with */.
Multi-line comments start with /* and end with */ . Any text between /* and */ will be ignored.
This should work:
(--.*)|(((/\*)+?[\w\W]+?(\*/)+))
