Question

I am trying to create RegEx to match C# comments (the double slash kind). The RegEx I have created almost works perfectly, except if there is a line that has just two backslashes and no actual comment, it starts matching the next line, which it shouldn’t do. Here is my regex:

(?![\n\r])\s?//[\w\W].+

Here is my test data:

using System;

// This is a comment

public class test
{
    // this is also a comment
    // Hello!
    //
}

My RegEx matches everything as expected except the line that has just the //. The RegEx I have matches the // and the final brace, which isn’t right.

Answer 1

This

(?![\n\r])\s?//.*?$

will match to the end of the line and no more.
