what is your expected output for
string input = "(Vaue 1) test + test(Vaue 2)bbb * aaa(Vaue 3)";

the expected output is: test + test bbb * aaa
everything without ()

Hi, just try the following function,

C#

private string FindMatch()
{
    string input = textBox1.Text.Trim();
    MatchCollection Matches = Regex.Matches(input, @"(\(.+?\))");

    foreach (Match match in Matches)
    {
        input = input.Replace(match.Value, "");
    }

    return input;
}

seem good and smart but i cant change the code behind i have to use the below exactly:

string input = "(Vaue 1) test + test(Vaue 2)bbb * aaa(Vaue 3)";
var matches = Regex.Matches(input, @"(?<=\().+?(?=\))")
.Cast<match>()
.Select(m => m.Value)
.ToList();

foreach (var item in matches)
{
Console.WriteLine(item);
}

If you can't change the code, then why are you asking us how to change the code?!

If you want to change the behaviour, then you need to change the code.

i am asking if there is a way to pick the string outside the ()

Did you try to use Regex.replace instead of Regex.matches ?

i don't want to use replace because it is fixed in the code and the regex can be entered from a textbox so i need to use replace

You should read again the documentation !
It is not more fixed with replace than with matches
