在visual studio 2012中查找所有注释行

Question

My project is developed by many people. Many of the developers have commented few of their codes

I have a lot of codes like

        //ServiceResult serviceResult = null;
        //JavaScriptSerializer serializer = null;
        //ErrorContract errorResponse = null;

They use // ,they don't use /**/ How can I find all such commented line in visual studio 2012 using regular expression

In that find it should not find any xml comments with ///

Answer 1

Simply try as

(?<!/)//.*(?!/)

• (?<!/) Negative Lookbehind - To check the // doesn't contains / as a preceding character
• //.* Matches any character including // except newline
• (?!/) Negative Lookahead - To check the // doesn't contains / as a next character

Answer 2

use this patten

(?<!/)//(?!/)

(?<!/) means it can not be / before //

(?!/) means it can not be / after //

Answer 3

Try this expression (?<!\\/)\\/\\/[^\\/].*

and for .NET as someone mentioned: (?<!/)//[^/].*

Answer 4

Try this regex:

^\s*(?<!/)(//(?!/).+)$

First group should give you the commented line.

Answer 5

This should cover most spacing cases and work in all VS versions. I believe look-behinds are only supported in VS2013.

^(?:\s|\t)*?//(?!/\s*<).+$

Answer 6

表达式应该是这样的：

//.*
