string input = @"Regex to find URLs unless they include a list of strings (Visual Studio search)
I have this the following expression which is working well for my needs:
(www\.)?[-a-zA-Z0-9@:%._\+~#=]{2,256}\.(com|net|info)\b([-a-zA-Z0-9@:%_\+.~#?&//=]*)
It does a pretty good job of finding URLs which are hardcoded in a large codebase. Obviously, it has some false positives for things like Using System.net, but some of the valid URLs don't include http(s):// unfortunately.
So now I want to be able to exclude certain things, including system.net (false positives) and google.com (common urls in comments).
How can I do this?
Ideally the list would just include google and system. Something like (!google|!system).
https://thisisaurl.com/";
RegexOptions options = RegexOptions.Multiline | RegexOptions.IgnoreCase;
foreach (Match m in Regex.Matches(input, pattern, options))
{
Console.WriteLine("'{0}' found at index {1}.", m.Value, m.Index);
}
}
}
