How to replace a regex with parentheses keeping the parentheses c#?

Question

I'm trying to do some regex replace on files and the strings that I'm trying to replace contains things like ()[]{} ...etc and I want to keep as it after the replace, here is a simple example

string str = @"This is a drill (2).";
string reseult = Regex.Replace(str, "\\((\\d+)\\)", "\\(<x>$1</x>\\)");

Console.WriteLine(reseult);
Console.ReadLine();

The result should output This is a drill (<x>2</x>). but it is outputting This is a drill \\(<x>2</x>\\). Same goes for []

Why is this happening and how to solve this without using the verbatim alternative?

Answer 1

string str = @"This is a drill (2).";
string reseult = Regex.Replace(str, "\\((\\d+)\\)", "(<x>$1</x>)");

Console.WriteLine(reseult);
Console.ReadLine();

Answer 2

string str = @"This is a drill (2).";
string reseult = Regex.Replace(str, "\\((\\d+)\\)", "(<x>$1</x>)");

Console.WriteLine(reseult);
Console.ReadLine();

You don't need to escape parentheses in the final part. It is not regex. Similarly for other braces you dont need to escape them either. Just use this.

string str = @"This is a drill (2).";
string reseult = Regex.Replace(str, "\\((\\d+)\\)", "{<x>$1</x>}");

Console.WriteLine(reseult);
Console.ReadLine();
