Replace

I have the below expression
string str1="<overmight express="\23\" optin="\test\">;

I want to replace optin value from test to advance.

I am unable to do this replace in c#. Could someone let me know.

Thanks

    someVar = RegEx.Replace(text_to_search, @"optin=""\\test\\""", @"optin=""\advance\""")

It's not working
string OptInFlag = "<OverLimitIntercept ExpirationDate=\"20090831\" OptIn=\"NotSeen\" NumberOfInterceptsDisplayed=\"0\" DateLastModified=\"20090719 09:32:23.938\" />";

                    
                  string someVar = System.Text.RegularExpressions.Regex.Replace(OptInFlag, @"OptIn=""\\NotSeen\\""", @"OptIn=""\Seen\""");
                  

Its not replacing the text to seen.

Do let me know

Here's my modified suggestion.  Note the extra \ chars in the match pattern was the issue.
using System;
namespace myapp
{
    class Class1
    {
        static void Main(string[] args)
        {
            string OptInFlag = "<OverLimitIntercept ExpirationDate=\"20090831\" OptIn=\"NotSeen\" NumberOfInterceptsDisplayed=\"0\" DateLastModified=\"20090719 09:32:23.938\" />";
            string someVar = System.Text.RegularExpressions.Regex.Replace(OptInFlag, @"(?<=<OverLimitIntercept[^>]*\sOptIn="")NotSeen(?="")", @"Seen");
            Console.WriteLine(someVar);
        }
    }
}
