Problem with Regex

[underwar]

I'm writing the following statement:

string sValue = @"(r11) , ";
string res = Regex.Match(sValue, @"[^,(\s)]+(\s)*,*(\s)*", RegexOptions.Compiled).Value;
Console.WriteLine(res);


I wish to get the string "(r11)" without the comma and the spaces.
Yet I get the string "r11" without the parentheses too.
What I'm doing wrong?
