Regex string definition issue

Question

I'm trying to make regex which will match all console.log("anything"); in the file. I wrote next pattern string:

@"(console\.log\(\"(.*)\"\)\;)"

The compiler doesn't compile code and says:

Method, Delegate or event is expected.

The problem is with stripslashing - " characters. But I don't know how to fix it, any ideas?

I use this pattern in method:

  js.RegexReplace(@"(console\.log\(\"(.*)\"\)\;)", "", RegexOptions.Singleline);

js is a string variable.

RegexReplace signature:

string RegexReplace(this string input, string pattern, string replacement, RegexOptions options)

Answer 1

You are mixing the verbatim and the escape character. That is not working as you expect, since you can't use \ to escape ", but need to use ".

Use this string with the verbatim:

@"(console\.log\(""(.*)""\)\;)"

Use this string, without the verbatim:

"(console\\.log\\(\"(.*)\"\\)\\;)"

Answer 2

Double double quotation marks:

@"(console\.log\(""(.*)""\);)"

EDIT: You do not have to escape ""s when using verbatim strings. So, the C# code will look like:

var pattern = @"(console\.log\(""(.*)""\);)";
